CVE-2026-50257
Description détaillée
A use-after-free flaw was found in the X.Org X server and Xwayland in miSyncDestroyFence(). A client that sets up multiple fence triggers can trigger a use-after-free function pointer call. An attacker would connect to the X server to set up a fence and await that fence, then a second X connection destroys the fence, causing the use-after-free. This may be used to crash the server, or for privilege escalation if the X server runs as root.

CVE-2026-50235
Lyrion Music Server 9.2.0 contains a reflected cross-site scripting vulnerability in advanced search parameters that fail to properly sanitize user input before displaying it in search forms. Attackers can inject malicious scripts through unfiltered search parameters to execute arbitrary JavaScript in users' browsers and steal session information.
CVE-2026-50234
Lyrion Music Server 9.2.0 contains a path traversal vulnerability that allows unauthenticated attackers to read arbitrary files by exploiting directory traversal in the web server context. Attackers can manipulate file path parameters to access sensitive files outside the intended directory structure.
CVE-2026-50233
Lyrion Music Server 9.2.0 contains an arbitrary directory listing vulnerability in its readdirectory query, exposed through both the CLI service (TCP port 9090) and the HTTP JSON-RPC endpoint (/jsonrpc.js). The query accepts a folder parameter and lists its contents with no restriction to the configured media directories and no authentication in the default configuration, allowing a remote, unauthenticated attacker to enumerate arbitrary locations on the host filesystem.
