{"id":"CVE-2026-33407","summary":"Wallos: SSRF via HTTP Proxy Environment Variable","details":"Wallos is an open-source, self-hostable personal subscription tracker. Prior to version 4.7.0, Wallos endpoints/logos/search.php accepts HTTP_PROXY and HTTPS_PROXY environment variables without validation, enabling SSRF via proxy hijacking. The server performs DNS resolution on user-supplied search terms, which can be controlled by attackers to trigger outbound requests to arbitrary domains. This issue has been patched in version 4.7.0.","aliases":["GHSA-hhjq-82f8-m6rc"],"modified":"2026-04-02T13:41:39.546732Z","published":"2026-03-24T17:40:58.666Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33407.json","cwe_ids":["CWE-918","CWE-922"],"cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33407.json"},{"type":"FIX","url":"https://github.com/ellite/Wallos/commit/e87387f0ebb540cd33e6dfda7181db9db650ecef#diff-d77202c5d47a3d7d4586e519f6f5e256da5fb2969fa8b9c75c399b2821e9de40"},{"type":"ADVISORY","url":"https://github.com/ellite/Wallos/security/advisories/GHSA-hhjq-82f8-m6rc"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-33407"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/ellite/wallos","events":[{"introduced":"0"},{"fixed":"6e52b68718cc0e0efb21bc504437f98f585a2c48"}],"database_specific":{"versions":[{"introduced":"0"},{"fixed":"4.7.0"}]}}],"versions":["v1.0.0","v1.0.1","v1.1.0","v1.10.0","v1.11.0","v1.11.1","v1.11.2","v1.11.3","v1.12.0","v1.12.1","v1.13.0","v1.14.0","v1.14.1","v1.15.0","v1.15.1","v1.15.2","v1.15.3","v1.16.0","v1.16.1","v1.16.2","v1.16.3","v1.17.0","v1.17.1","v1.17.2","v1.17.3","v1.18.0","v1.18.1","v1.18.2","v1.18.3","v1.19.0","v1.2.0","v1.20.0","v1.20.1","v1.20.2","v1.21.0","v1.21.1","v1.22.0","v1.23.0","v1.24.0","v1.25.0","v1.25.1","v1.26.0","v1.26.1","v1.26.2","v1.27.0","v1.27.1","v1.27.2","v1.28.0","v1.29.0","v1.29.1","v1.3.0","v1.3.1","v1.4.0","v1.4.1","v1.5.0","v1.6.0","v1.7.0","v1.8.0","v1.8.1","v1.8.2","v1.8.3","v1.9.0","v1.9.1","v2.0.0","v2.1.0","v2.10.0","v2.11.0","v2.11.1","v2.11.2","v2.12.0","v2.13.0","v2.14.0","v2.14.1","v2.14.2","v2.15.0","v2.16.0","v2.16.1","v2.17.0","v2.18.0","v2.19.0","v2.19.1","v2.19.2","v2.19.3","v2.2.0","v2.20.0","v2.20.1","v2.21.0","v2.21.1","v2.21.2","v2.21.3","v2.22.0","v2.22.1","v2.23.0","v2.23.1","v2.23.2","v2.24.0","v2.24.1","v2.25.0","v2.26.0","v2.27.0","v2.27.1","v2.27.2","v2.27.3","v2.28.0","v2.29.0","v2.29.1","v2.29.2","v2.3.0","v2.30.0","v2.30.1","v2.31.0","v2.31.1","v2.32.0","v2.33.0","v2.33.1","v2.34.0","v2.35.0","v2.36.0","v2.36.1","v2.36.2","v2.37.0","v2.37.1","v2.38.0","v2.38.1","v2.38.2","v2.38.3","v2.39.0","v2.39.1","v2.4.0","v2.4.1","v2.4.2","v2.40.0","v2.41.0","v2.42.0","v2.42.1","v2.42.2","v2.43.0","v2.43.1","v2.44.0","v2.44.1","v2.45.0","v2.45.1","v2.45.2","v2.46.0","v2.46.1","v2.47.0","v2.47.1","v2.48.0","v2.48.1","v2.49.0","v2.49.1","v2.5.0","v2.5.1","v2.5.2","v2.50.0","v2.50.1","v2.51.0","v2.51.1","v2.52.0","v2.52.1","v2.52.2","v2.6.0","v2.6.1","v2.7.0","v2.8.0","v2.9.0","v3.0.0","v3.0.1","v3.0.2","v3.1.0","v3.1.1","v3.2.0","v3.3.0","v3.3.1","v4.0.0","v4.1.0","v4.1.1","v4.2.0","v4.3.0","v4.4.0","v4.4.1","v4.5.0","v4.6.0","v4.6.1","v4.6.2"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-33407.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:N/VA:H/SC:N/SI:N/SA:N"}]}
