Prior to 1.18.0, corsProxyMiddleware forwards req.params.url directly into fetch(url, ...). It only blocks circular requests to its own host and does not enforce destination allowlist or private/loopback restrictions, enabling SSRF. This vulnerability is fixed in 1.18.0.","published":"2026-05-29T17:43:07.425Z","modified":"2026-08-07T11:31:06.696524699Z","cvss":null,"epss":{"score":0.00375,"percentile":0.30227,"asOf":"2026-08-09"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"sillytavern","fixedVersion":"1.18.0"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/44xxx/CVE-2026-44652.json"},{"type":"ADVISORY","url":"https://github.com/SillyTavern/SillyTavern/security/advisories/GHSA-ccfq-2454-f5xw"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-44652"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T11:31:06.696524699Z"}}
