CVE-2025-71377

Popis

stoatchat (delta) versions before 20250210-1 (0.8.2) contain a logic error in the query messages route. When fetching messages -nearby- another message, the database query can be given a message limit of zero, which the database interprets as -no limit-. A remote unauthenticated attacker can craft nearby message fetch requests to download an entire channel-s message history in a single expensive request, and can send many such requests in parallel, resulting in denial of service through resource exhaustion.
