Plex Urges Immediate Updates After Patching Multiple Undisclosed Security Flaws

Plex patched multiple undisclosed flaws in Media Server 1.43.3 and Desktop 1.115.0, urging all users to update immediately.

Plex released fixes in Plex Media Server 1.43.3 and Plex Desktop 1.115.0 for multiple undisclosed security flaws, with CVE identifiers requested and details not yet published. Censys data shows more than 360,000 devices expose the Plex Media Server web interface. Past Plex flaws saw real exploitation, including CVE-2020-5741 (CVSS 7.2), used to implant a keylogger on a LastPass employee's home computer during the 2022 breach, and CVE-2025-34158 (CVSS 8.5), an authentication bug patched in August 2025.

Multiple VLC Media Player Vulnerabilities Allow Attackers to Corrupt or Read Heap Memory

Two VLC 3.0 flaws, CVE-2026-56711 (heap corruption, CVSS 8.6) and CVE-2026-73324 (memory leak), let crafted PNGs or RTSP playlists corrupt memory or leak data.

Hap Security researcher Fabian Wahle disclosed two VLC Media Player flaws on September 9, 2026, affecting versions 3.0.0 through 3.0.23. CVE-2026-56711 (CVSS 8.6) is an integer overflow and out-of-bounds write in the AllocatePicture function, exploitable via a crafted PNG with oversized IHDR dimensions, potentially causing crashes or code execution. CVE-2026-73324 (CVSS 6.9) lets a malicious RTSP server read adjacent heap memory through an unterminated 4096-byte response line, triggerable via a realrtsp playlist URL. No patched release is confirmed yet; users should avoid untrusted media files, playlists, and RTSP streams.

Risky Bulletin: Ukraine's top prosecutor resigns amid scam call center scandal

Ukraine's top prosecutor Ruslan Kravchenko resigned after NABU arrested a deputy for taking bribes protecting scam call centers running fake investment platforms.

Ukraine's anti-corruption bureau NABU arrested Serhiy Kropyva, Deputy Head of International Cooperation at the Prosecutor General's Office, alleging officials took monthly protection fees from a network of 100-500 scam call centers luring victims into fake investment platforms, with bribes reportedly growing from $700,000 to $3.5 million per month. Prosecutor General Ruslan Kravchenko resigned on Monday, calling it a political decision, while Kropyva was fired with bail set at 120 million hryvnias ($2.7 million) and over 100 call centers shut down in the past month. The newsletter also briefly covers a cyberattack crippling more than 80 Luxembourg medical practices via payment vendor BMS Engineering, ShinyHunters' claimed theft of 200,000 Florida DMV driver records, a cyberattack on the American Meteor Society, and school closures in Springfield, Massachusetts.

Jellyfin 12.0 Released With Security Fixes for Unauthorized File Access and XSS Flaws

Jellyfin 12.0 fixes unauthorized file access and web client XSS flaws, but requires careful upgrades due to breaking database migrations and plugin changes.

The open-source media server release prevents crafted requests from reading files outside designated directories, blocks unauthorized re-runs of the setup wizard, rejects plugin packages with unsafe names, strengthens parental control enforcement, and fixes cross-site scripting vulnerabilities in browser-based administration and media access workflows. Upgrades require a manual backup because the database schema migration is irreversible; supported paths start from version 10.10.7 or 10.11.x, and duplicate case-insensitive usernames will break migration. The release also retires legacy /emby/ and /mediabrowser/ routes, disables deprecated authentication by default, and targets .NET 10, requiring plugin rebuilds.

Survey finds one filesystem MCP server vulnerable to a symlink-based sandbox escape while four others are defended by design.

A survey of five filesystem MCP servers assessed how each enforces its path-confinement boundary against symlink escapes in recursive directory walkers. The iceener/files-stdio-mcp-server is vulnerable to a read-side sandbox escape. The other four are defended by design or make no confinement claim. The author describes the vulnerability class as small but real.

iceener/files-stdio-mcp-server: sandbox escape in fs_search via a symlinked directory (recursive walker validates only the top level)

iceener/files-stdio-mcp-server allows a read-side sandbox escape: fs_search follows symlinked directories while the recursive walker validates confinement only at the top level.

A vulnerability report describes a read-side sandbox escape in iceener/files-stdio-mcp-server, an MCP server for text-based file access that explicitly promises 'Sandboxed filesystem access. Only these paths are available'. The fs_search tool can follow symlinked directories outside the allowed paths, and the recursive directory-listing walker used by fs_search (and by fs_read) validates confinement only at the top level. The same flaw affects fs_read's directory-listing walker. No CVE identifier was assigned in the provided report text.

How MCP Servers Can Expose Enterprise Secrets

MCP servers holding AI agent credentials risk secret exposure via plaintext configs, credential sprawl, prompt injection, and over-permissioning; mitigations include centralization and least privilege.

The article examines how Model Context Protocol servers, which hold API keys, tokens, and service-account credentials for AI agents, can leak enterprise secrets. Documented exposure paths include plaintext credentials in config files, ungoverned credential sprawl, prompt injection, over-permissioning, and untrusted third-party servers. It cites CVE-2025-6514 in mcp-remote (400,000+ downloads), where a malicious server triggered OS command injection leading to remote code execution. Recommended mitigations include centralized secret stores, short-lived auto-rotated credentials, least privilege, and human approval for sensitive actions.
