CVE-2026-31976
CriticalSummary
Podatność CVE-2026-31976 dotyczy GitHub Action dla Xygeni Scanner, gdzie atakujący wykorzystał skompromitowane dane uwierzytelniające do wstrzyknięcia obfuskowanego kodu powłoki do pliku action.yml. Chociaż wnioski o pull requesty zostały zablokowane przez zasady ochrony gałęzi, atakujący zmienił tag v5, aby wskazywał na złośliwy commit, co umożliwiło wykonanie złośliwego kodu w workflow.
Risk Assessment
Organizacja jest narażona na poważne ryzyko, ponieważ każdy workflow korzystający z xygeni/xygeni-action@v5 w okresie od 3 do 10 marca 2026 roku mógł wykonać złośliwy kod, co prowadziło do nieautoryzowanego wykonania poleceń na runnerze CI.
Recommendation
Zaleca się natychmiastowe zaktualizowanie tagu do wersji, która nie jest zainfekowana oraz przeprowadzenie audytu użycia GitHub Actions w celu wykrycia i usunięcia potencjalnych zagrożeń związanych z tą podatnością.

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)
xygeni-action is the GitHub Action for Xygeni Scanner. On March 3, 2026, an attacker with access to compromised credentials created a series of pull requests (#46, #47, #48) injecting obfuscated shell code into action.yml. The PRs were blocked by branch protection rules and never merged into the main branch. However, the attacker used the compromised GitHub App credentials to move the mutable v5 tag to point at the malicious commit (4bf1d4e19ad81a3e8d4063755ae0f482dd3baf12) from one of the unmerged PRs. This commit remained in the repository's git object store, and any workflow referencing @v5 would fetch and execute it. This is a supply chain compromise via tag poisoning. Any GitHub Actions workflow referencing xygeni/xygeni-action@v5 during the affected window (approximately March 3–10, 2026) executed a C2 implant that granted the attacker arbitrary command execution on the CI runner for up to 180 seconds per workflow run.
