CVE-2026-86188
HighCVSS 7.2Summary
AVideo with YPTSocket plugin enabled contains a cross-site scripting vulnerability allowing unauthenticated attackers to execute arbitrary JavaScript in other users' browsers via the websocket callback mechanism. Attackers can send crafted socket messages with callback names resolving to global functions like avideoConfirmHTML that accept untrusted data and assign it to innerHTML, achieving script execution in the victim's origin without authentication or user interaction.
Risk Assessment
The risk includes data theft, session hijacking, and propagation of malicious code within the application context.
Recommendation
It is recommended to update AVideo and the YPTSocket plugin to patched versions and validate/sanitize data passed to callbacks.
Other vulnerabilities in AVideo
See all- CVE-2026-86187Medium
WWBN AVideo generates passwords for external-login accounts using rand() instead of a cryptographic generator, producing only 31-bit integers. Attackers with access to password hashes can recover plaintext passwords in minutes through offline brute-force attacks due to unsalted MD5-based hashing.
- CVE-2026-86186Medium
AVideo API fails to enforce rate limits when clients send a bot User-Agent header, allowing attackers to bypass all eight protected operations including login brute-force protection. Attackers can send requests with a bot User-Agent to disable rate limiting and perform unlimited password guessing attempts against any account from a single IP address.
- CVE-2026-85163Medium
AVideo through commit c91b5975d contains a server-side request forgery vulnerability in the EPG parser that allows authenticated uploaders to fetch arbitrary internal URLs. An attacker can supply an internal URL via the epg_link parameter, which is only syntax-validated and later fetched server-side without SSRF protection.
- CVE-2026-85162Medium
AVideo through commit c91b5975d contains a cross-site request forgery vulnerability in plugin/Live/saveLive.php that lacks forbidIfNotPost and forbidIfInvalidToken protections. Attackers can craft malicious image tags to overwrite authenticated streamers' RTMP keys, passwords, and titles, hijacking live broadcasts.
- CVE-2026-85161Medium
AVideo through commit c91b5975d contains a cross-site request forgery vulnerability in removePoster.php that lacks forbidIfNotPost or forbidIfInvalidToken checks. Attackers can craft malicious image tags to delete authenticated victims' live poster and thumbnail files via GET requests.
- CVE-2026-85160High
AVideo through commit c91b5975d contains a cross-site request forgery and path traversal vulnerability in stopLive.php that allows attackers to delete directories by exploiting missing token validation and unsanitized key parameter concatenation. Attackers can craft an image tag with a traversal payload like key=../../videos to trigger recursive deletion of the videos directory when an admin visits a malicious page.
- CVE-2026-85158Medium
AVideo through commit c91b5975d contains a reflected cross-site scripting vulnerability in videoEmbeded.php that echoes the link parameter inside an HTML comment with zero escaping. Attackers can close the comment with --> and inject arbitrary JavaScript that executes when victims visit the crafted embed URL.
- CVE-2026-84187High
AVideo contains a missing authentication vulnerability in plugin/Live/on_publish.php that allows unauthenticated attackers to mark arbitrary scheduled broadcasts as failed by sending crafted POST requests with schedule identifiers. Attackers can exploit the unguarded RTMP callback endpoint to modify scheduled broadcast status fields by supplying fabricated stream keys matching the pattern -ps-<N>, silently canceling any scheduled live broadcast without credentials or authorization.
- CVE-2026-83595High
AVideo contains a cross-site request forgery vulnerability in plugin/API/set.json.php that allows attackers to perform state-changing actions by crafting GET requests that bypass CSRF protection. Attackers can navigate a victim's browser to a malicious URL with API parameters to delete videos, deactivate accounts, or modify playlists without user interaction.
- CVE-2026-43884High
AVideo is an open source video platform that is vulnerable to SSRF attacks in versions up to 29.0. Two endpoints improperly validate user-supplied URLs, allowing an attacker to redirect to internal resources.
