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-2026-104466 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-2026-104466/ (Markdown: https://insights.sbomify.com/CVE-2026-104466/index.md)","id":"CVE-2026-104466","markdown":"https://insights.sbomify.com/CVE-2026-104466/index.md","name":"CVE-2026-104466","record":{"aliases":["GHSA-7pv9-pwm8-cwwr","GHSA-jjg5-rgm8-pvxr"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"YesWiki","requires_auth":"low_privilege","summary":"Attackers can inject JavaScript via markdown image URLs in YesWiki, potentially executing code in administrators' browsers.","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:L/VI:L/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 formatters/wakka.php that allows users who can edit pages or post comments to inject event handlers by placing quotes in markdown image URLs.
