Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-36091 in the wild and no public exploit code.\n\nAffected product: Otrs Otrs. 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-2021-36091/ (Markdown: https://insights.sbomify.com/CVE-2021-36091/index.md)","id":"CVE-2021-36091","markdown":"https://insights.sbomify.com/CVE-2021-36091/index.md","name":"CVE-2021-36091","record":{"aliases":["DEBIAN-CVE-2021-36091","GHSA-mxpc-p9xr-9j86","UBUNTU-CVE-2021-36091"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"OTRS ticketing system","requires_auth":"low_privilege","summary":"Agents can view calendar appointments without proper permissions, exposing sensitive scheduling data in OTRS systems.","user_interaction":"required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"OTRS","cpe":[{"product":"otrs","vendor":"otrs"}],"cvss":{"score":3.5,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"},{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"Agents are able to list appointments in the calendars without required permissions.
