The workflow .github/workflows/python_checks.yml inserts ${{ github.event.pull_request.title }} directly into double-quoted bash strings in four steps across four jobs, passing it to run_tests_model_gen_and_load.py. Because the shell expands the title before Python runs, an attacker can break out of the quotes and run arbitrary commands on the runner, and the pull_request trigger fires for PRs targeting any branch with no further access gate.","solution":"This vulnerability is fixed by the 998e390e80a7e8192d7849b7784bc113dbd190ad commit.","labels":["security","industry"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-44723","publishedAt":"2026-05-26T17:16:46.680Z","cveId":"CVE-2026-44723","cweIds":["CWE-78","CWE-1336"],"cvssScore":"5","cvssSeverity":"medium","severity":"medium","attackType":["supply_chain"],"issueType":"vulnerability","affectedPackages":null,"affectedPackageNames":null,"affectedPackageRefs":null,"affectedVendors":[],"affectedVendorsRaw":["Vowpal Wabbit"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":"Vowpal Wabbit command execution through pull request title in GitHub workflow","headlinePromptVersion":"h1","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:N/A:N","attackVector":"network","attackComplexity":"low","privilegesRequired":"low","userInteraction":"none","exploitMaturity":"unknown","epssScore":0.00585,"epssCheckedAt":"2026-10-14T12:12:41.724Z","kevDateAdded":null,"advisoryAliases":null,"affectedPackagesSource":null,"affectedPackagesCheckedAt":"2026-10-10T03:48:07.096Z","patchAvailable":null,"disclosureDate":"2026-05-26T17:16:46.680Z","capecIds":["CAPEC-88"],"crossRefCount":0,"attackSophistication":"trivial","impactType":["integrity","confidentiality"],"aiComponentTargeted":"framework","llmSpecific":false,"classifierConfidence":0.8,"researchCategory":null,"atlasIds":["AML.T0010"]}}
