What is CVE-2026-100526?
CVE-2026-100526 is a medium-severity path traversal vulnerability in openclaw discord, published on 26 Sep 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
OpenClaw's Discord integration (npm package @openclaw/discord) before version 2026.9.3 could lose the sender-scoped media policy in the emoji and sticker upload actions before loading a local file. A sender permitted to invoke those actions could cause OpenClaw to read a host path that the same sender's configured media roots would otherwise reject, placing bytes from an out-of-policy local file into an outbound emoji or sticker upload. Exploitation requires access to the guild asset action and knowledge or derivation of a useful local path; the issue does not permit unrestricted filesystem browsing or code execution. The issue is fixed in @openclaw/discord 2026.9.3.
Weakness: CWE-862
