An unauthenticated attacker can guess Unix timestamps in file names to download stickers from any session. _Summary, check and fix written by a model from the sources; labelled as such._ ## How to check - Check the installed WPPConnect Server version against the range in the advisory: through `2.10.76` is affected. - Look for a publicly reachable `/files` static route on the server that serves `file.webp` paths. ## Fix - Patch: see the linked GitHub fix; the fixed version is not stated in the sources provided. ## Timeline - 2026-11-05T19:40:35+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-123197 ## Documents - [advisory] Third-party advisory: www.vulncheck.com https://www.vulncheck.com/advisories/wppconnect-server-through-2.10.76-unauthenticated-sticker-media-disclosure-via-files - [fix] Patch: github.com https://github.com/wppconnect-team/wppconnect-server/commit/bf1faac7a14892207348c3dc5f6e03ed180e09e8 ## From the sources WPPConnect Server through 2.10.76 contains a missing authentication vulnerability that allows unauthenticated attackers to read decrypted sticker media through the /files static mount. Attackers can enumerate Unix timestamps in GET /files/file.webp requests to retrieve stickers from any session, bypassing per-session token checks. --- _Free to read, with fair use of about 60 pages a minute.
