An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-3136 in the wild and no public exploit code.\n\nAffected product: Google Cloud Cloud Build. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-3136/ (Markdown: https://insights.sbomify.com/CVE-2026-3136/index.md)","id":"CVE-2026-3136","markdown":"https://insights.sbomify.com/CVE-2026-3136/index.md","name":"CVE-2026-3136","record":{"aliases":["GHSA-p8rp-xfq6-8f8m"],"analysis":{"component_type":"cloud_service","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Google Cloud Build","requires_auth":"none","summary":"A remote attacker can execute arbitrary code in the build environment due to improper authorization in GitHub Trigger Comment Control.","user_interaction":"required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GoogleCloud","cpe":[{"product":"cloud_build","vendor":"google"}],"cvss":{"score":8.6,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:L/SI:L/SA:L/U:Clear","version":"4.0"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"}],"description":"An improper authorization vulnerability in GitHub Trigger Comment Control in Google Cloud Build prior to 2026-1-26 allows a remote attacker to execute arbitrary code in the build environment.\n\nThis vulnerability was patched on 26 January 2026, and no customer action is needed.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Google Cloud Build Comment Control Bypass","id":"CVE-2026-3136","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"CodeAstro Food Ordering System food_ordering.exe stack-based overflow","id":"CVE-2026-3137"},"packages":[],"prev":{"headline":"itsourcecode News Portal Project add-category.php sql injection","id":"CVE-2026-3135"},"products":["Cloud Build"],"published":"2026-03-03","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-03-04","vendors":["Google Cloud"]},"summary":"A remote attacker can execute arbitrary code in the build environment due to improper authorization in GitHub Trigger Comment Control.","url":"https://insights.sbomify.com/CVE-2026-3136/"}
