Prior to commit 75cb095, an unrestricted Server-Side Request Forgery (SSRF) vulnerability allows any authenticated user to force the Stringer server to send arbitrary HTTP/HTTPS requests to internal networks, localhost services, and cloud metadata endpoints (e.g. AWS IMDS 169.254.169.254). When self-service signup is enabled (Setting::UserSignup), even a low-privileged registered user can exploit this to scan internal services or steal cloud IAM credentials. This issue has been patched via commit 75cb095.","categories":["Unclassified"],"product":"stringer","vendor":"stringer-rss","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-55160","source_modified_at":"2026-09-28T18:35:30.003Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"stringer","vendor":"stringer-rss","versions":[{"version":"< 75cb0955919a362ac49d23c8a14892d0f59ea1c4","status":"affected"}],"defaultStatus":null}],"fixed_versions":[],"cvss":7.6,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00278,"percentile":0.19174,"score_date":"2026-10-23"},"published_at":"2026-09-28T17:52:24.490Z","modified_at":"2026-09-28T18:35:30.003Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-55160","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-28T18:35:30.003Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-55160","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/stringer-rss/stringer/security/advisories/GHSA-496x-437q-h35q","tags":["exploit"]},{"source":"CVE List","url":"https://github.com/stringer-rss/stringer/pull/1548","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/stringer-rss/stringer/commit/75cb0955919a362ac49d23c8a14892d0f59ea1c4","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"no","technical_impact":"partial","assessed_at":"2026-09-28T18:33:57.068972Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-09-28T18:35:30.003Z","content_hash":"2bd6f979501cf13374c8b43d0d68c59e4efc7cadd913daed18761f22d4e59b0a"}}
