  1. CVE-2026-82805 4.3 Moyenne

    Typora

    A vulnerability was found in Typora up to 1.13.8/1.14.6. This vulnerability affects unknown code of the component Mermaid Rendering Engine. The manipulation of the argument classDef/style results in cross site scripting. The attack may be launched remotely. The exploit has been made public and could be used. Upgrading to version 1.14.8 is able to resolve this issue. You should upgrade the affected component. The vendor was contacted early, responded in a very professional manner and quickly released a fixed version of the affected product.

  2. CVE-2026-75798 5.3 Moyenne

    Unknown AI Engine

    The AI Engine WordPress plugin before 3.7.2 does not perform an authorisation check on one of its administration-only features, relying instead on a token it hands out to anonymous visitors, allowing unauthenticated attackers to run AI queries of their own choosing against the site owner's configured provider account.

  3. CVE-2026-75797 7.7 Élevée

    Unknown AI Engine

    The AI Engine WordPress plugin before 3.7.2 does not confine a caller-supplied URL when mapping it to a local filesystem path before reading the file and forwarding its contents to an external service, allowing users with a subscriber-level account to read arbitrary files from the server and exfiltrate them off-host. Reaching the issue at subscriber level requires a non-default public API feature to be enabled; otherwise the same issue is reachable by an administrator, which on multisite allows a non-super subsite administrator to read the network-shared configuration and its secrets.

  4. CVE-2026-19094 5.3 Moyenne

    Unknown Tutor LMS

    The Tutor LMS WordPress plugin before 4.0.6 does not validate values used to build a database query, and does not restrict which template file a request may load, allowing unauthenticated users to inject SQL and to read question and answer content belonging to courses that are not publicly available. The injected text reaches the query as grammar rather than as data, and on the database engines tested it does not yield extraction of arbitrary data, so the confidentiality impact is the disclosed course content rather than the database at large.

  5. CVE-2026-75796 7.2 Élevée

    Unknown AI Engine

    The AI Engine WordPress plugin before 3.6.1 does not verify that the requesting user is authorized to act on the targeted account before performing privileged user management operations, allowing users with the Administrator role on a Multisite sub-site to take over any account on the network, including the Network Administrator's.

  6. CVE-2026-54739 6.9 Moyenne

    LemmyNet lemmy

    Lemmy is a link aggregator and forum for the fediverse. Prior to 0.19.19 and 1.0.0-beta.1, Lemmy's login endpoint in crates/api/api/src/local_user/login.rs returns different errors depending on whether the username_or_email value exists. LocalUserView::find_by_email_or_name propagates a NotFound response for an unknown account, while an existing account with a wrong password returns LemmyErrorType::IncorrectLogin. This observable response discrepancy, including HTTP 404 for a nonexistent account and HTTP 400 for an incorrect password on an existing account, allows an unauthenticated attacker to confirm registered usernames or email addresses and use the results for targeted credential attacks or social engineering. This issue is fixed in versions 0.19.19 and 1.0.0-beta.1.

  7. CVE-2026-18202 6.8 Moyenne

    Unknown JetEngine

    The JetEngine WordPress plugin before 3.8.14 adds SVG to the site-wide list of allowed upload types without sanitising the file contents, allowing users with the upload files capability, such as Authors, to upload a file containing malicious JavaScript that executes in the browser of any user who opens it (Stored Cross-Site Scripting). On multisite, this also overrides an upload-type restriction set by the network administrator.

  8. CVE-2026-17019 6.1 Moyenne

    Unknown JetEngine

    The JetEngine WordPress plugin before 3.8.13.1 does not sanitise uploaded SVG files before storing and serving them, and does not adequately restrict who can upload them, allowing unauthenticated attackers to upload a file containing malicious JavaScript that executes in the browser of any user who opens it (Stored Cross-Site Scripting).

  9. CVE-2026-16955 5.0 Moyenne

    Unknown AI Engine

    The AI Engine WordPress plugin before 3.6.6 does not confine a caller-supplied file path before reading it and forwarding the contents to an external service, allowing users with a subscriber-level account to read arbitrary files from the server and exfiltrate them off-host. Reaching the issue at subscriber level requires a non-default public API feature to be enabled; otherwise the same issue is reachable by an administrator, which on multisite allows a non-super subsite administrator to read the network-shared configuration and its secrets.

  10. CVE-2026-16953 4.8 Moyenne

    Unknown AI Engine

    The AI Engine WordPress plugin before 3.6.4 does not verify ownership of a guest's uploaded chatbot files before deletion, authorising the action solely by a client-supplied session cookie value, so an unauthenticated attacker who obtains a victim's session identifier and file reference can delete that victim's uploaded files.

  11. CVE-2026-12501 5.3 Moyenne

    Unknown WP Travel Engine

    The WP Travel Engine WordPress plugin before 6.8.2 does not verify that an incoming PayPal payment notification was sent to the site's configured merchant account, nor that the paid amount matches the order total, before marking a booking as paid, allowing unauthenticated attackers to mark bookings as fully paid using a token payment made to an attacker-controlled account.
