Upgrade LobeChat to version 2.2.10-canary.15 or later, where this vulnerability is fixed. No other mitigation is indicated.
Description
LobeChat versions before 2.2.10-canary.15 contain a regular expression denial of service (ReDoS) vulnerability. Authenticated attackers can supply a malicious GitHub repository URL path with catastrophic-backtracking regex patterns during skill import. This causes synchronous execution of a complex regex in the findSkillMd function, blocking the Node.js event loop and denying service to all users for tens of seconds per request. The issue is fixed in version 2.2.10-canary.15.
