CVE-2026-39386 (GCVE-0-2026-39386)

Title
Neko has Self-service Privilege Escalation for Authenticated Users
Summary
Neko is a a self-hosted virtual browser that runs in Docker and uses WebRTC In versions 3.0.0 through 3.0.10 and 3.1.0 through 3.1.1, any authenticated user can immediately obtain full administrative control of the entire Neko instance (member management, room settings, broadcast control, session termination, etc.). This results in a complete compromise of the instance. The vulnerability has been patched in v3.0.11 and v3.1.2. If upgrading is not immediately possible, the following mitigations can reduce risk: Restrict access to trusted users only (avoid granting accounts to untrusted parties); ensure all user passwords are strong and only shared with trusted individuals; run the instance only when needed; avoid leaving it continuously exposed; place the instance behind authentication layers such as a reverse proxy with additional access controls; disable or restrict access to the /api/profile endpoint if feasible; and/or monitor for suspicious privilege changes or unexpected administrative actions. Note that these are temporary mitigations and do not fully eliminate the vulnerability. Upgrading is strongly recommended.

Title
Insufficient file checks in m1k1o/blog
Summary
m1k1o/blog is a lightweight self-hosted facebook-styled PHP blog. Errors from functions `imagecreatefrom*` and `image*` have not been checked properly. Although PHP issued warnings and the upload function returned `false`, the original file (that could contain a malicious payload) was kept on the disk. Users are advised to upgrade as soon as possible. There are no known workarounds for this issue.
