An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2021-26085 in the wild since at least 28 Mar 2022, including in ransomware campaigns.\n\nAffected product: Atlassian Confluence Data Center. 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-2021-26085/ (Markdown: https://insights.sbomify.com/CVE-2021-26085/index.md)","id":"CVE-2021-26085","markdown":"https://insights.sbomify.com/CVE-2021-26085/index.md","name":"CVE-2021-26085","record":{"aliases":["GHSA-8mjc-qhq2-3xm8"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Atlassian Confluence","requires_auth":"none","summary":"Remote attackers can view restricted resources via an arbitrary file read vulnerability in the /s/ endpoint of Atlassian Confluence Server.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"atlassian","cpe":[{"product":"confluence_data_center","vendor":"atlassian"},{"product":"confluence_server","vendor":"atlassian"}],"cvss":{"score":5.3,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-425","name":"Direct Request"}],"description":"Affected versions of Atlassian Confluence Server allow remote attackers to view restricted resources via a Pre-Authorization Arbitrary File Read vulnerability in the /s/ endpoint.
