This meant anyone who could connect directly to SillyTavern could fake these headers to log in as any user, including administrators, without a password, but only if SSO was explicitly enabled in the configuration.","solution":"Update SillyTavern to version 1.18.0 or later, which fixes the vulnerability.","labels":["security"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-44649","publishedAt":"2026-05-29T19:16:24.720Z","cveId":"CVE-2026-44649","cweIds":["CWE-290","CWE-306","CWE-346","CWE-807"],"cvssScore":"9.8","cvssSeverity":"critical","severity":"critical","attackType":["supply_chain"],"issueType":"vulnerability","affectedPackages":null,"affectedVendors":[],"affectedVendorsRaw":["SillyTavern"],"classifierModel":"claude-haiku-4-5-20251001","classifierPromptVersion":"v3","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","attackVector":"network","attackComplexity":"low","privilegesRequired":"none","userInteraction":"none","exploitMaturity":"unknown","epssScore":0,"patchAvailable":null,"disclosureDate":"2026-05-29T19:16:24.720Z","capecIds":["CAPEC-115"],"crossRefCount":0,"attackSophistication":"trivial","impactType":["integrity","confidentiality"],"aiComponentTargeted":"api","llmSpecific":true,"classifierConfidence":0.95,"researchCategory":null,"atlasIds":["AML.T0010"]}}
