Summary
plugNmeet Server through version 2.5.2 contains a path traversal vulnerability in the whiteboard conversion endpoint, allowing any meeting participant to read server files via crafted filePath values. Attackers can use ../ sequences to convert text or office documents into page images, then fetch them unauthenticated through /download/uploadedFile/.
Risk Assessment
Unauthorized access to sensitive server files can lead to data leakage, including configuration or other sensitive resources. The vulnerability can be exploited by any meeting participant.
Recommendation
Update plugNmeet Server to a version newer than 2.5.2. If updating is not possible, restrict access to the conversion endpoint and monitor for suspicious requests.

Vulnerability in the JSSE component of Oracle Java SE, Oracle GraalVM for JDK, and Oracle GraalVM Enterprise Edition. It is easily exploitable by an unauthenticated attacker with network access, leading to unauthorized creation, deletion, or modification of critical data as well as unauthorized access to critical data. The vulnerability also applies to Java deployments that load and run untrusted code in a sandbox (e.g., Java Web Start applications or applets).

Postiz signs its session, invitation and password reset tokens with one shared secret and without any marker of what a token is for. A route that refreshes the credentials of a browser-extension channel signed data taken from the request itself and stored the result where the requesting user can read it back, allowing a user to obtain a validly signed token containing any claims they choose, accepted as a session, an organization invitation with a chosen role, a password reset or an enterprise provisioning token.

Python has added a denylist for known compromised certificates to the "ssl" module to ensure user safety even without certificate revocation configured. Known compromised certificates will automatically be rejected regardless of the SSLContext policy configuration.
- CVE-2026-115932Critical
In Postiz, a media path that is not a web address is treated as a file on the server's disk without verifying it lies inside the upload directory. A registered user can store a crafted media path with a post and cause the publishing worker to read an arbitrary file and send it as an attachment to a Discord server the user controls. The same unconfined reads are reachable through two further routes, including file existence checks and backend memory exhaustion; self-registration is open by default.
