An attacker can read any file the server can access by passing an arbitrary file path, then upload that file to an attacker-controlled server. This is especially dangerous because the default setup exposes the tool over the network without authentication, making it remotely exploitable.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://github.com/advisories/GHSA-p6hp-93wp-fh6p","publishedAt":"2026-09-22T20:35:21.000Z","cveId":"CVE-2026-77262","cweIds":null,"cvssScore":null,"cvssSeverity":"high","severity":"high","attackType":["data_extraction"],"issueType":"vulnerability","affectedPackages":["mcp-atlassian@< 0.22.0 (fixed: 0.22.0)"],"affectedVendors":[],"affectedVendorsRaw":["mcp-atlassian","Atlassian"],"classifierModel":"claude-haiku-4-5-20251001","classifierPromptVersion":"v3","cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":"unknown","epssScore":0,"patchAvailable":true,"disclosureDate":"2026-09-22T20:35:21.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"trivial","impactType":["confidentiality"],"aiComponentTargeted":"agent","llmSpecific":false,"classifierConfidence":0.92,"researchCategory":null,"atlasIds":null}}
