  1. CVE-2026-15369 9.8 Critique

    Addify Custom User Registration Fields for WooCommerce

    The Custom User Registration Fields for WooCommerce plugin for WordPress is vulnerable to Privilege Escalation in versions up to, and including, 2.2.3. This is due to the plugin accepting an attacker-controlled afreg_select_user_role value from the unauthenticated WooCommerce Store API /wc/store/v1/checkout request in the af_reg_checkout_data_to_order_meta_data_block() function, persisting it in order meta, and then passing it directly to WP_User::add_role() in the af_reg_custom_order_processing_function() function (hooked to woocommerce_thankyou) without validating against the plugin's admin-configured allowed role list. This makes it possible for unauthenticated attackers to elevate their privileges to Administrator by creating an account during checkout with a modified JSON body specifying administrator (or any other role slug) as the desired role. Note: The exploit requires the "User Role Selection" setting to be enabled.

  2. CVE-2026-82460 9.8 Critique

    coderaiser cloudcmd

    Cloud Commander before 19.20.2 contains a directory traversal vulnerability in REST file-operation and markdown endpoints that fails to properly validate path normalization. Attackers can use path traversal sequences to read, write, move, or copy files outside the configured root directory.

  3. CVE-2026-82456 10.0 Critique

    argoproj-labs argocd-mcp

    argocd-mcp 0.8.0 binds its HTTP transport to every network interface and accepts MCP sessions without requiring caller credentials when ARGOCD_API_TOKEN is configured. Attackers who can reach the listener can invoke the full tool surface using the operator's stored token to create applications, request syncs, and modify Argo CD resources.

  4. CVE-2026-82455 – Non évaluée Rejetée

    Rejected reason: The RubyGems maintainers determined that the reported symlink-following behavior during gem extraction is not a security vulnerability, so no vulnerability exists for this record to describe.

  5. CVE-2026-82454 9.1 Critique

    omnivore-app omnivore

    The Omnivore API (packages/api) before the fix in commit abf53d6 contains an authentication bypass in Apple sign-in token verification. The decodeAppleToken function extracted the 'alg' field from the attacker-supplied JWT header and passed it as the sole allowed algorithm to jwt.verify(). Using jsonwebtoken v8 (which does not validate key/algorithm compatibility), an attacker can set alg=HS256 and sign a forged token using Apple's publicly available RSA public key as the HMAC secret, bypassing signature verification and impersonating any Apple-linked account.

  6. CVE-2026-82452 9.8 Critique

    iot-ecology rust-iot-platform

    rust-iot-platform through commit 5df942ab contains an authentication bypass vulnerability where most REST API routes lack authentication guards in their handler signatures. Unauthenticated attackers can create, update, list, retrieve, and delete user accounts by directly accessing unprotected endpoints without providing valid credentials.

  7. CVE-2026-82448 9.8 Critique

    Shinobi Systems Shinobi

    Shinobi before commit 5a76c74f contains a hardcoded connection key in the child node service that allows unauthenticated attackers to execute arbitrary database queries. Attackers reaching the child node port can present the hardcoded key during WebSocket handshake, then dispatch SQL queries through the onWebSocketDataFromChildNode handler to read and modify user records and camera configuration.

  8. CVE-2026-14494 9.8 Critique

    bdthemes SigmaForms Pro – AI Generated Forms

    The Sigma Forms Pro plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 1.4.5 via the handle_form_submission function. This is due to the plugin dynamically granting the unfiltered_upload capability to all users during form submissions and bypassing MIME type validation when allowed_file_types is not configured. This makes it possible for unauthenticated attackers to execute code on the server. Several default pre-built templates including Job Application, Support Ticket, and Wholesale Application have file upload fields with no file type restrictions configured by design, making this vulnerability immediately exploitable upon installation.

  9. CVE-2026-80725 9.8 Critique

    Linux

    In the Linux kernel, the following vulnerability has been resolved: net: gro: properly validate BIG TCP aggregation criteria When GRO attempts to aggregate packets beyond GRO_LEGACY_MAX_SIZE (64KB), BIG TCP should only be permitted for plain IPv4 TCP and plain IPv6 TCP (with sufficient MAC header room to insert the temporary HBH jumbo header). However, commit b1a78b9b9886 ("net: add support for ipv4 big tcp") loosened the check in skb_gro_receive(), leading to several issues: 1. skb_gro_receive() checked skb_headroom(p) instead of the actual space before the MAC header (p->mac_header). Because skb_headroom(p) includes mac_len, crafted frames (e.g. injected via AF_PACKET) can pass the check with p->mac_header < 8 bytes. When ipv6_gro_complete() inserts the temporary HBH jumbo header, the memmove() starts before skb->head, causing an out-of-bounds write and wrapping skb->mac_header. 2. It allowed non-IP protocols such as software VLAN (ETH_P_8021Q / ETH_P_8021AD) to aggregate beyond 64KB because p->protocol != ETH_P_IPV6 was true. 3. It checked p->encapsulation instead of NAPI_GRO_CB(skb)->encap_mark, allowing encapsulated flows (e.g. SIT / IPv6-in-IPv4) to aggregate beyond 64KB. Fix skb_gro_receive() to strictly enforce: - NAPI_GRO_CB(skb)->proto == IPPROTO_TCP - Not encapsulated (!NAPI_GRO_CB(skb)->encap_mark && !p->encapsulation) - Protocol must be either ETH_P_IP or ETH_P_IPV6 - If ETH_P_IPV6, p->mac_header must be at least sizeof(struct hop_jumbo_hdr) Returning -E2BIG from skb_gro_receive() ensures that packets which cannot become BIG TCP are cleanly flushed at <= 64KB and delivered intact without dropping. This issue does not exist in mainline (7.0+) because the subsystem was rewritten in commit 81be30c1f5f2 ("net/ipv6: Drop HBH for BIG TCP on RX side"), making this fix relevant only for older stable branches like 6.18.y.

  10. CVE-2026-77012 9.3 Critique

    Unknown 爱采集数据采集和发布插件

    The 爱采集数据采集和发布插件 WordPress plugin through 1.0.0 does not require a per-install secret for one of its unauthenticated endpoints, relying on a hardcoded default, and does not validate the URLs or destination paths it is given, allowing unauthenticated attackers to read arbitrary files from the server, force it to issue arbitrary requests and retrieve the responses, and write attacker-supplied content outside the uploads directory.

  11. CVE-2026-16947 9.1 Critique

    Unknown Total processing card payments for WooCommerce

    The Total processing card payments for WooCommerce WordPress plugin through 7.3 does not validate a user-supplied path before using it to build a server-side verification request, and does not verify the authenticity of the response, allowing unauthenticated attackers to redirect that request to an arbitrary host (disclosing the merchant's payment-gateway credentials) and to forge a success response that marks arbitrary WooCommerce orders as paid.

  12. CVE-2026-16259 9.8 Critique

    Unknown Uix UserCenter

    The Uix UserCenter WordPress plugin through 1.0.3 does not verify that the account being modified through an unauthenticated profile-update action belongs to the requester, and it authenticates that action with a token whose signing key is hardcoded and identical across every install, allowing unauthenticated attackers to forge a token for any user, overwrite an administrator's email and password, and take over the account.

  13. CVE-2026-10522 9.8 Critique

    Unknown MemberHero

    The MemberHero WordPress plugin through 6.9 does not restrict which account fields can be supplied during its frontend registration process, allowing unauthenticated attackers to register a new user with an arbitrary role, including Administrator, leading to a full site takeover. Version 6.9 is advertised as resolving this issue, but the fix is incomplete and the current version remains exploitable by unauthenticated attackers to obtain administrator access and to take over existing accounts. No version that fully addresses the issue is available at the time of this advisory. Mitigation: deactivate and remove the MemberHero WordPress plugin through 6.9 until a version that fully resolves this issue is released. If the MemberHero WordPress plugin through 6.9 must stay active, disable public registration, restrict access to the registration functionality, and monitor the site for unexpected administrator accounts.

  14. CVE-2026-55891 0.0 Non évaluée

    PrivateBin

    PrivateBin is an online pastebin where the server has zero knowledge of pasted data. Prior to 2.0.5, Request::getRequestUri() in lib/Request.php passes $_SERVER['REQUEST_URI'] through FILTER_SANITIZE_URL, which does not remove quotation marks, angle brackets, or apostrophes, and Controller::_init() stores the attacker-controlled value in Controller::$_urlBase. Controller::_jsonld() in lib/Controller.php then uses str_replace() to insert that value without JSON escaping into js/types.jsonld, js/paste.jsonld, and the other JSON-LD templates used by /?jsonld= and /?pasteid. A raw quotation mark delivered by an HTTP client, proxy, or structured-data crawler that does not normalize the request target can break out of the JSON string and inject arbitrary key-value data into a CORS-open application/ld+json response. The jsonld branch in Controller::__construct() returns before _setCacheHeaders(), so the response also lacks X-Content-Type-Options: nosniff, Content Security Policy, X-Frame-Options, and Referrer-Policy. Direct script execution was not demonstrated, but manipulated responses can affect structured-data consumers or combine with less strict clients. This issue is fixed in version 2.0.5.

  15. CVE-2026-51663 9.8 Critique

    Incorrect access control in the getWiFiApcliScan function of TOTOLINK T6 4.1.5cu.748_B20211015 allows unauthenticated attackers to trigger wireless scans and retrieve AP-client scan results via sending a crafted POST request to /cgi-bin/cstecgi.cgi.

  16. CVE-2026-51661 9.1 Critique

    Incorrect access control in the getPortForwardRules function of TOTOLINK T6 4.1.5cu.748_B20211015 allows unauthenticated attackers to obtain port-forwarding rules via sending a crafted POST request to /cgi-bin/cstecgi.cgi.

  17. CVE-2026-3627 9.1 Critique

    IBM Concert

    IBM Concert 1.0.0 through 2.3.1 is vulnerable to SQL injection. A remote attacker could send specially crafted SQL statements, which could allow the attacker to view, add, modify, or delete information in the back-end database.

  18. CVE-2026-19295 9.9 Critique

    IBM Langflow OSS · Langflow langflow

    IBM Langflow OSS 1.0.0 through 1.11.1 allows an authenticated attacker to execute arbitrary operating system commands in the server process by saving a flow with a crafted type field value and triggering a build of a wrapper flow that references it. This allowed privilege escalation from "authenticated flow user" to arbitrary OS-level command execution under the server process identity, bypassing the LANGFLOW_ALLOW_CUSTOM_COMPONENTS=false policy control.

  19. CVE-2026-19286 9.8 Critique

    IBM Langflow OSS · Langflow langflow

    IBM Langflow OSS 1.0.0 through 1.11.1 could allow a remote attacker to execute arbitrary code due to improper enforcement of security restrictions on the A2A public endpoint.

  20. CVE-2026-18527 9.9 Critique

    IBM Administration Runtime Expert for i

    IBM Administration Runtime Expert for i 1R1M0 IBM Application Runtime Expert (ARE) for i could allow a remote attacker to gain elevated privileges, caused by ARE GUI component processing. An unauthenticated attacker can exploit this vulnerability to execute actions under another user's authenticated profile gaining elevated privileges on the IBM i system.
