Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-49279 exists.\n\nAffected packages and fixed versions:\n- wwbn/avideo (Packagist): affected all versions up to 29.0; no fix listed\n- wwbn/avideo (Packagist): affected all versions up to 29.0; 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-2026-49279/ (Markdown: https://insights.sbomify.com/CVE-2026-49279/index.md)","id":"CVE-2026-49279","markdown":"https://insights.sbomify.com/CVE-2026-49279/index.md","name":"CVE-2026-49279","record":{"aliases":["GHSA-2fhx-q92v-5fhv"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["account_takeover","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Video platform","requires_auth":"low_privilege","summary":"Authenticated attackers can execute arbitrary JavaScript via WebSocket messages, leading to session hijacking and account takeover in the AVideo platform.","user_interaction":"not_required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":7.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"WWBN AVideo is an open source video platform. Versions 29.0 and below contain a Stored XSS vulnerability through the autoEvalCodeOnHTML parameter in the MessageSQLite WebSocket Handler. The MessageSQLite.php handler only strips autoEvalCodeOnHTML from $json['msg'], but msgToResourceId() reads from $msg['json'] with higher priority. An attacker can place the XSS payload in the json key instead of msg, bypassing the sanitization entirely. An authenticated attacker can execute arbitrary JavaScript in any connected user's browser session via the WebSocket messaging system, stealing session cookies and authentication tokens, taking over accounts through session hijacking, and chaining with CSRF to perform admin actions on the victim's behalf, in the default SQLite WebSocket backend configuration.
