CVE-2026-31871
CriticalSummary
W Parse Server, przed wersjami 9.6.0-alpha.5 i 8.6.31, występuje podatność na wstrzykiwanie SQL w adapterze pamięci masowej PostgreSQL podczas przetwarzania operacji Increment na zagnieżdżonych polach obiektów przy użyciu notacji kropkowej. Nazwa podklucza jest interpolowana bezpośrednio do literałów ciągów SQL bez odpowiedniego zabezpieczenia.
Risk Assessment
Atakujący, który ma możliwość wysyłania żądań zapisu do REST API Parse Server, może wstrzykiwać dowolne zapytania SQL, co może prowadzić do wykonania nieautoryzowanych poleceń lub odczytu danych z bazy danych, omijając CLP i ACL. Tylko wdrożenia PostgreSQL są narażone na to zagrożenie.
Recommendation
Zaleca się aktualizację do wersji 9.6.0-alpha.5 lub 8.6.31, aby usunąć tę podatność. Należy również przeanalizować i zabezpieczyć istniejące aplikacje przed potencjalnymi atakami SQL injection.

- 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)
Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to 9.6.0-alpha.5 and 8.6.31, a SQL injection vulnerability exists in the PostgreSQL storage adapter when processing Increment operations on nested object fields using dot notation (e.g., stats.counter). The sub-key name is interpolated directly into SQL string literals without escaping. An attacker who can send write requests to the Parse Server REST API can inject arbitrary SQL via a crafted sub-key name containing single quotes, potentially executing commands or reading data from the database, bypassing CLPs and ACLs. Only Postgres deployments are affected. This vulnerability is fixed in 9.6.0-alpha.5 and 8.6.31.
