Prior to 8.32.0, the webhook middleware spawns a goroutine that holds a reference to the request's echo.Context after the synchronous handler returns ErrAsyncProcess and Echo recycles the context back to its sync.Pool. When a concurrent request claims the recycled context, c.Reset() clears the store. If the webhook goroutine reaches hardTimeoutMiddleware at that moment, an unchecked type assertion on a nil store entry panics outside any recover() scope, crashing the Gotenberg process. Any anonymous caller reaches the webhook path (default webhook-deny-list filters only the webhook destination, not the submitter). A single-source stress of ~24 webhook requests plus ~60 GET /version requests crashes the process in about two seconds. This vulnerability is fixed in 8.32.0."}], "lastModified": "2026-05-18T13:02:23.307", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:thecodingmachine:gotenberg:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "F6763958-60E0-49F9-9B7B-35A1B94622D8", "versionEndExcluding": "8.32.0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
