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.","state":0,"publishedAt":"2026-09-28T17:52:24.49+00:00","modifiedAt":"2026-09-28T18:35:30.003+00:00","affected":[{"ecosystem":"Vendor product","name":"stringer","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"stringer-rss\",\n                    \"product\": \"stringer\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 75cb0955919a362ac49d23c8a14892d0f59ea1c4\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:L","score":7.6,"severity":"HIGH"}],"references":["https://github.com/stringer-rss/stringer/security/advisories/GHSA-496x-437q-h35q","https://github.com/stringer-rss/stringer/pull/1548","https://github.com/stringer-rss/stringer/commit/75cb0955919a362ac49d23c8a14892d0f59ea1c4"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-55160","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-55160","identifiers":["CVE-2026-55160"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
