An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-8727 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- tomasnorre/crawler (Packagist): affected all versions; fixed in 11.0.13\n- tomasnorre/crawler (Packagist): affected all versions; fixed in 11.0.13\n- tomasnorre/crawler (Packagist): affected from 12.0.0; fixed in 12.0.11\n- tomasnorre/crawler (Packagist): affected from 12.0.0; fixed in 12.0.11\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-2026-8727/ (Markdown: https://insights.sbomify.com/CVE-2026-8727/index.md)","id":"CVE-2026-8727","markdown":"https://insights.sbomify.com/CVE-2026-8727/index.md","name":"CVE-2026-8727","record":{"aliases":["GHSA-jr8m-x4p7-p3v5"],"analysis":{"component_type":"cms_plugin","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"TYPO3 Crawler extension","requires_auth":"high_privilege","summary":"An attacker with admin privileges can achieve remote code execution on TYPO3 servers by injecting malicious serialized objects into crawled responses.","user_interaction":"required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"TYPO3","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:H/UI:A/VC:H/VI:H/VA:H/SC:L/SI:L/SA:L","version":"4.0"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"The Crawler extension passes the X-T3Crawler-Meta response header from crawled URLs directly to PHP's unserialize().
