Prior to 0.30.3, the AliasVault server API favicon extractor validates a user-supplied hostname with a first DNS lookup but allows the HTTP client to perform a second DNS lookup when connecting. An authenticated low-privileged user operating an attacker-controlled authoritative DNS server can return a public address during validation and a private address during connection, causing a publicly reachable self-hosted server to issue HTTP or HTTPS requests to internal hosts. A valid image response is returned in Base64 form, while other responses can expose limited timing and error information for internal-network reconnaissance. Exploitation requires a publicly reachable self-hosted instance with public registration enabled, an authenticated AliasVault account, an attacker-controlled authoritative DNS server, and a resolver that permits rebinding; default checks limit requests to ports 80 and 443. The browser extensions, web application, and mobile applications are not affected. This issue is fixed in version 0.30.3.","state":0,"publishedAt":"2026-10-15T18:23:33.174+00:00","modifiedAt":"2026-10-16T17:11:53.157+00:00","affected":[{"ecosystem":"Vendor product","name":"aliasvault","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"aliasvault\",\n                    \"product\": \"aliasvault\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 0.30.3\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"ghcr.io/aliasvault/aliasvault","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"aliasvault\",\n                    \"product\": \"ghcr.io/aliasvault/aliasvault\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 0.30.3\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"ghcr.io/aliasvault/api","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"aliasvault\",\n                    \"product\": \"ghcr.io/aliasvault/api\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 0.30.3\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"ghcr.io/lanedirt/aliasvault-api","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"aliasvault\",\n                    \"product\": \"ghcr.io/lanedirt/aliasvault-api\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 0.30.3\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:N/A:N","score":6.3,"severity":"MEDIUM"}],"references":["https://github.com/aliasvault/aliasvault/security/advisories/GHSA-7hm6-fj4m-pf6f","https://github.com/aliasvault/aliasvault/pull/2311","https://github.com/aliasvault/aliasvault/commit/7eb4fee71f4582cfc80b8daea421b99d6aa9f814","https://github.com/aliasvault/aliasvault/commit/90ea7d6bb4c74ca169ee1dde3ca38b08bd0966ed","https://github.com/aliasvault/aliasvault/releases/tag/0.30.3"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-94621","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-94621","identifiers":["CVE-2026-94621"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
