Prior to version 1.17.0, in src/endpoints/search.js, the hostname is checked against /^\\d+\\.\\d+\\.\\d+\\.\\d+$/. This only matches literal dotted-quad IPv4 (e.g. 127.0.0.1, 10.0.0.1). It does not catch: localhost (hostname, not dotted-quad), [::1] (IPv6 loopback), and DNS names resolving to internal addresses (e.g. localtest.me -> 127.0.0.1). A separate port check (urlObj.port !== '') limits exploitation to services on default ports (80/443), making this lower severity than a fully unrestricted SSRF. This issue has been patched in version 1.17.0."}],"source":{"advisory":"GHSA-wm7j-m6jm-8797","discovery":"UNKNOWN"}},"adp":[{"references":[{"url":"https://github.com/SillyTavern/SillyTavern/security/advisories/GHSA-wm7j-m6jm-8797","tags":["exploit"]}],"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-04-02T17:47:59.886274Z","id":"CVE-2026-34526","options":[{"Exploitation":"poc"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-04-02T17:48:03.787Z"}}]}}
