In versions 2.3.3 and below, untrusted data is extracted from the user-controlled HTTP Proxy-Authorization header and passed to Extension::try_from and flows into parse_ttl_extension where it is parsed as a TTL value. If an attacker supplies a TTL of zero (e.g. by using a username such as 'configuredUser-ttl-0'), the modulo operation 'timestamp % ttl' will cause a division by zero panic, causing the server to crash causing a denial-of-service. This is fixed in version 2.4.0."}]}, "problemtype": {"problemtype_data": [{"description": [{"lang": "en", "value": "CWE-369"}]}]}, "data_version": "4.0", "CVE_data_meta": {"ID": "CVE-2025-54581", "ASSIGNER": "security-advisories@github.com"}}, "impact": {}, "publishedDate": "2025-07-30T20:15Z", "configurations": {"nodes": [], "CVE_data_version": "4.0"}, "lastModifiedDate": "2025-07-30T20:15Z"}
