  1. 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.

  2. 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.

  3. 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.
