Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-54049 exists.\n\nAffected packages and fixed versions:\n- org.sakaiproject.conversations:sakai-conversations-impl (Maven): affected from 23.0 up to 23.3; no fix listed\n- org.sakaiproject.conversations:sakai-conversations-impl (Maven): affected from 23.0 up to 23.3; no fix listed\n- org.sakaiproject.kernel:sakai-kernel-impl (Maven): affected from 23.0 up to 23.3; no fix listed\n- org.sakaiproject.kernel:sakai-kernel-impl (Maven): affected from 23.0 up to 23.3; no fix listed\n- org.sakaiproject.rubrics:rubrics-impl (Maven): affected from 23.0 up to 23.3; no fix listed\n- org.sakaiproject.rubrics:rubrics-impl (Maven): affected from 23.0 up to 23.3; no fix listed\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-2026-54049/ (Markdown: https://insights.sbomify.com/CVE-2026-54049/index.md)","id":"CVE-2026-54049","markdown":"https://insights.sbomify.com/CVE-2026-54049/index.md","name":"CVE-2026-54049","record":{"aliases":["GHSA-w2x5-gv52-9ccv"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Sakai LMS","requires_auth":"low_privilege","summary":"Authenticated users can inject malicious scripts into Sakai Conversations posts, executing code in other users' browsers.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Sakai is a Collaboration and Learning Environment (CLE). From versions 23.0 to before 23.5, and versions 25.0 to before 25.3, the Sakai Conversations tool stores topic and post messages without HTML sanitization, and the frontend renders them using LitElement's unsafeHTML() directive, resulting in stored cross-site scripting (XSS). Any authenticated user with access to a site that has the Conversations tool enabled can inject arbitrary HTML and JavaScript that executes in the browsers of all other users who view that topic or post.
