CVE-2026-31852
CriticalSummary
Jellyfin to system multimedialny typu open-source. Workflow code-quality.yml w projekcie jellyfin/jellyfin-ios jest podatny na wykonanie dowolnego kodu poprzez pull requesty z forku, co może prowadzić do przejęcia repozytorium oraz wycieku poufnych danych.
Risk Assessment
Podatność ta stwarza poważne ryzyko dla organizacji, umożliwiając pełne przejęcie repozytorium, ataki na łańcuch dostaw w Apple App Store oraz kompromitację całej organizacji Jellyfin.
Recommendation
Zaleca się monitorowanie pull requestów oraz przeglądanie workflow GitHub Actions, aby zminimalizować ryzyko związane z tą podatnością.

- CVE-2026-107935Critical
A path traversal vulnerability was found in gvproxy, the network forwarder provided by the gvisor-tap-vsock package. The unauthenticated /services/forwarder/expose endpoint does not validate the caller-supplied socket path, allowing an attacker to delete arbitrary files on the host system.
- CVE-2026-107909Critical
A heap-based out-of-bounds write in the ws_read_frame function (src/bolt/ws.c) and the buffer_apply_mask function (src/bolt/buffer.c) in FalkorDB before 4.20.0 allows a remote unauthenticated attacker to cause a denial of service and possibly corrupt heap memory by sending a WebSocket frame with a 64-bit extended payload length to the Bolt port. The payload length is not bounded, and the only bounds check in buffer_apply_mask is an ASSERT(), which is compiled out in release builds, so the function XORs memory beyond the end of the receive buffer with the attacker-supplied mask key. Only deployments that enable the Bolt endpoint (BOLT_PORT, disabled by default) are affected.
- CVE-2026-107908Critical
A heap-based out-of-bounds write in the BoltReadHandler function (src/bolt/bolt_api.c) in FalkorDB before 4.20.0 allows a remote unauthenticated attacker to cause a denial of service and possibly execute arbitrary code by sending a Bolt RESET message with an attacker-chosen chunk size to the Bolt port. The handler checks the size only with ASSERT(), which is compiled out in release builds, then computes a destination pointer from the wire-supplied 16-bit size and moves buffered data up to about 64 KiB backwards past the start of the read buffer. Only deployments that enable the Bolt endpoint (BOLT_PORT, disabled by default) are affected.
Original NVD description (English source)
Jellyfin is an open-source media system. The code-quality.yml GitHub Actions workflow in jellyfin/jellyfin-ios is vulnerable to arbitrary code execution via pull requests from forked repositories. Due to the workflow's elevated permissions (nearly all write permissions), this vulnerability enables full repository takeover of jellyfin/jellyfin-ios, exfiltration of highly privileged secrets, Apple App Store supply chain attack, GitHub Container Registry (ghcr.io) package poisoning, and full jellyfin organization compromise via cross-repository token usage. Note: This is not a code vulnerability, but a vulnerability in the GitHub Actions workflows. No new version is required for this GHSA and end users do not need to take any actions.
