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-2026-89257 exists.\n\nAffected product: WWBN AVideo. 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-2026-89257/ (Markdown: https://insights.sbomify.com/CVE-2026-89257/index.md)","id":"CVE-2026-89257","markdown":"https://insights.sbomify.com/CVE-2026-89257/index.md","name":"CVE-2026-89257","record":{"aliases":["GHSA-7r9w-g597-h25f","GHSA-gf2v-r8wx-ghqj"],"analysis":{"component_type":"web_application","fix_type":"no_fix_stated","impacts":["data_modify"],"network_reachable":"yes","non_default_config":true,"product_category":"Video platform","requires_auth":"low_privilege","summary":"Authenticated users can delete arbitrary category assets due to missing ownership checks, requiring non-default configuration.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-639","name":"Authorization Bypass Through User-Controlled Key"}],"description":"AVideo through 29.0 contains an insecure direct object reference (IDOR) vulnerability in objects/categoryDeleteAssets.json.php.

It omits the Category::userCanEditCategory() ownership check enforced by the sibling Category::delete(). On installations where the non-default usersCanCreateNewCategories setting is enabled, an authenticated non-admin user with the canUpload capability can send a POST request with an arbitrary category ID and recursively delete any category's on-disk asset directory (icons/images).
