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-2026-104461 exists.\n\nAffected product: yeswiki. 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-2026-104461/ (Markdown: https://insights.sbomify.com/CVE-2026-104461/index.md)","id":"CVE-2026-104461","markdown":"https://insights.sbomify.com/CVE-2026-104461/index.md","name":"CVE-2026-104461","record":{"aliases":["GHSA-67v5-7pfv-pp9m","GHSA-c49r-h57h-8wfx"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["account_takeover","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"YesWiki","requires_auth":"low_privilege","summary":"Authenticated users can upload malicious SVG files to execute scripts in the wiki origin, potentially compromising administrator accounts.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":5.1,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N","version":"4.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"YesWiki before 4.6.7 contains a stored cross-site scripting vulnerability in the Bazar FileField, which validates only the upload's file extension and never calls HtmlPurifierService::cleanFile, so SVG files are stored verbatim and served inline as image/svg+xml.
