Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-54501 in the wild and no public exploit code.\n\nAffected product: webrecorder browsertrix. 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-2026-54501/ (Markdown: https://insights.sbomify.com/CVE-2026-54501/index.md)","id":"CVE-2026-54501","markdown":"https://insights.sbomify.com/CVE-2026-54501/index.md","name":"CVE-2026-54501","record":{"aliases":["GHSA-47vv-v544-r985"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Web archiving crawler","requires_auth":"low_privilege","summary":"Attackers with crawler permissions can inject commands via Git URLs in custom behaviors, leading to arbitrary code execution and data compromise.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":9.4,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","version":"4.0"},"cwes":[{"id":"CWE-88","name":"Improper Neutralization of Argument Delimiters in a Command"},{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"},{"id":"CWE-77","name":"Improper Neutralization of Special Elements used in a Command"},{"id":"CWE-250","name":"Execution with Unnecessary Privileges"},{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Browsertrix is a high-fidelity, browser-based crawling service for web archiving that can be self-hosted or used through Webrecorder's hosted instance. From 1.15.0 until 1.22.8, Browsertrix improperly sanitizes Git URLs specified as Custom Behaviors, allowing command injection through /api/orgs/*/crawlconfigs/validate/custom-behavior. A user with crawler or administrator permission on the specific instance can supply a crafted Git URL that executes arbitrary operating-system commands in the backend pod. Open registration or hosted free-trial access can make the required role broadly obtainable. Successful exploitation can expose, modify, or delete application database records, archived items, browser profiles, storage data, proxy credentials, and other configured service data.
