CVE-2020-14381
HighSummary
W jądrze Linuxa znaleziono lukę w implementacji futex, która pozwala lokalnemu atakującemu na uszkodzenie pamięci systemowej lub eskalację uprawnień podczas tworzenia futex na systemie plików, który ma być odmontowany. Luka ta wpływa na poufność, integralność oraz dostępność systemu.
Risk Assessment
Zagrożenie dla organizacji polega na możliwości naruszenia poufności danych, integralności systemu oraz jego dostępności, co może prowadzić do poważnych konsekwencji operacyjnych.
Recommendation
Zaleca się aktualizację jądra Linuxa do najnowszej wersji, aby usunąć tę lukę oraz monitorowanie systemów w celu wykrycia potencjalnych prób ataków.

PyJWT is a Python implementation of JSON Web Token standards. Prior to version 2.14.0, is_pem_format in jwt/utils.py does not recognize every PEM representation accepted by the cryptography loader. When an application mixes HMAC and asymmetric algorithms and supplies a mutated public-key PEM as raw key bytes, HMACAlgorithm.prepare_key treats the unrecognized asymmetric public key as an HMAC secret. An attacker who knows the public key can forge authenticated HMAC tokens. This issue is fixed in version 2.14.0.

Joomla Extension - ordasoft.com - Unauthenticated SQL Injection in Book Library (Free) < 6.4.6. The books() function in site/booklibrary.php reads the field and direction request parameters and passes each through a function called protectInjectionWithoutQuote(), whose only real protection is a keyword blacklist that, on detecting the literal substring select, wraps the value in $db->quote() instead of rejecting it. The value is then concatenated directly into an unquoted ORDER BY clause, a position where quoting provides no protection at all. Reaching the vulnerable code path requires two conditions: a first request to prime session-stored sort defaults, and a trailing decoy comment (-- xselect) that satisfies the blacklist’s substring check without altering the payload’s effect.

Joomla Extension - ordasoft.com - Unauthenticated SQL Injection in Vehicle Manager (Free) < 6.5.8. The site/vehiclemanager.php file reads the order_field and order_direction sort parameters at three separate anonymous-reachable frontend entry points (category listing, search, and the all-vehicles listing) through a sanitizing function that applies real escaping, but the value is then placed into an unquoted ORDER BY clause, where escaping has no protective effect.
- CVE-2026-100752Critical
Joomla Extension - ordasoft.com - Unauthenticated SQL Injection in Real Estate Manager (Free) < 6.7.9. The site/realestatemanager.php file builds the ORDER BY clause of three separate frontend property-listing queries (category browsing, search results, and the full property listing) from a request-controlled order_field parameter, concatenated directly into an unquoted SQL clause with no allow-list of real column names and no cast.
- CVE-2026-49994Critical
Bluehood monitors local bluetooth activity. Prior to version 0.7.1, when auth_enabled is set in Bluehood, only the HTML page handlers enforced session validation. The /api/* handlers (settings, devices, groups, per-device endpoints including /api/device/{mac}/notes) called no auth check at all. A network attacker reachable on the dashboard port could read Bluetooth tracking data and modify application state — including the heartbeat URL, prune retention, device groups, and per-device notes — without a session cookie. This issue has been patched in version 0.7.1.
- CVE-2026-86102Critical
An OS command injection vulnerability in the WatchGuard AP internal API service allows an attacker with network access to the AP to execute arbitrary shell commands on the underlying operating system.
Original NVD description (English source)
A flaw was found in the Linux kernel’s futex implementation. This flaw allows a local attacker to corrupt system memory or escalate their privileges when creating a futex on a filesystem that is about to be unmounted. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.
