{"id":"GHSA-rw58-wc66-99g4","summary":"Duplicate Advisory: GitPython 3.1.59: --no-index bypasses diff unsafe-option protections and enables a blind local-file content oracle","details":"## Duplicate Advisory\n\nThis advisory has been withdrawn because it is a duplicate of GHSA-whh4-5q6c-9v3x. This link is maintained to preserve external references.\n\n## Original Description\nGitPython 3.1.59 fails to restrict the --no-index option in the high-level diff API, allowing attackers to read arbitrary filesystem paths as repository operands. Attackers can combine --no-index with -I/--ignore-matching-lines to create a content-dependent Boolean oracle, repeatedly querying local files to recover single-line secrets through distinguishable success or error responses.","aliases":["CVE-2026-87818"],"modified":"2026-09-30T23:45:04.071942879Z","published":"2026-09-09T12:32:15Z","withdrawn":"2026-09-30T23:28:15Z","database_specific":{"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2026-09-30T23:28:15Z","nvd_published_at":"2026-09-09T12:17:16Z","cwe_ids":["CWE-88"]},"references":[{"type":"WEB","url":"https://github.com/gitpython-developers/GitPython/security/advisories/GHSA-whh4-5q6c-9v3x"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-87818"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/gitpython-3.1.59-local-file-content-oracle-via-no-index"}],"affected":[{"package":{"name":"gitpython","ecosystem":"PyPI","purl":"pkg:pypi/gitpython"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.1.59"}]}],"versions":["3.1.59","3.1.60","3.1.61","3.1.62","3.2.0"],"database_specific":{"last_known_affected_version_range":"\u003c 3.1.60","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/09/GHSA-rw58-wc66-99g4/GHSA-rw58-wc66-99g4.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
