From 3.5.0 to before 3.5.2, tools/quota-statusline.sh (introduced in v3.5.0) interpolates Claude Code's hook stdin payload directly into a Python triple-quoted string literal. A ''' byte sequence in any user-controlled field of the payload closes the literal early and lets following bytes execute as Python in the user's Claude Code process. This vulnerability is fixed in 3.5.2.","cvss_v4":{"vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:L/SC:N/SI:N/SA:N","score":8.6},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","score":7.8},"cwes":["CWE-78","CWE-94"],"references":["https://github.com/cnighswonger/claude-code-cache-fix/issues/108","https://github.com/cnighswonger/claude-code-cache-fix/pull/110","https://github.com/cnighswonger/claude-code-cache-fix/security/advisories/GHSA-g3xq-3gmv-qq8g","https://github.com/cnighswonger/claude-code-cache-fix/issues/108","https://github.com/cnighswonger/claude-code-cache-fix/security/advisories/GHSA-g3xq-3gmv-qq8g"],"products":["cnighswonger:claude-code-cache-fix"],"source":"nvd","synced_at":"2026-10-19T22:36:28.938604137+00:00"},"epss":{"cve":"CVE-2026-45136","score":0.00188,"percentile":0.08442,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-g3xq-3gmv-qq8g","url":"https://osv.dev/vulnerability/GHSA-g3xq-3gmv-qq8g","summary":"claude-code-cache-fix vulnerable to local code execution via Python triple-quote injection in tools/quota-statusline.sh","modified":"2026-06-09T00:00:19.227252611Z","packages":[{"ecosystem":"npm","name":"claude-code-cache-fix","purl":"pkg:npm/claude-code-cache-fix","ranges":[">=3.5.0 <3.5.2"],"fixed":["3.5.2"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
