An attacker can exploit it over the internet without logging in, 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-2026-43882 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-2026-43882/ (Markdown: https://insights.sbomify.com/CVE-2026-43882/index.md)","id":"CVE-2026-43882","markdown":"https://insights.sbomify.com/CVE-2026-43882/index.md","name":"CVE-2026-43882","record":{"aliases":["GHSA-mwgh-92m2-wvhv"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["data_modify","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Video platform","requires_auth":"none","summary":"Unauthenticated CRLF injection in AVideo allows attackers to spoof calendar events via malicious ICS files, enabling high-credibility phishing.","user_interaction":"required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":4.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-93","name":"Improper Neutralization of CRLF Sequences"}],"description":"WWBN AVideo is an open source video platform. In versions up to and including 29.0, the unauthenticated plugin/Scheduler/downloadICS.php endpoint passes attacker-controlled title, description, and joinURL parameters into Scheduler::downloadICS(), which builds an ICS calendar file via the ICS helper class. ICS::escape_string() (objects/ICS.php:167-169) only escapes , and ; and does NOT neutralize CR/LF, so attacker CRLF bytes inside a property value break out and inject arbitrary ICS lines — including END:VEVENT / BEGIN:VEVENT pairs that add entire attacker-controlled calendar events. Because the malicious .ics file is served from the victim's trusted AVideo origin, this enables high-credibility calendar phishing: forged meetings with attacker-chosen SUMMARY, URL, LOCATION, and DESCRIPTION landing in the victim's calendar after import.
