CVE-2026-24884
HighSummary
Biblioteka Compressing w wersjach 2.0.0 oraz 1.10.3 i wcześniejszych ma lukę, która pozwala na ekstrakcję archiwów TAR z symbolicznymi linkami bez weryfikacji ich celów. Atakujący może wykorzystać tę lukę, aby zapisać pliki w dowolnych lokalizacjach na systemie plików hosta.
Risk Assessment
Luka ta może prowadzić do nadpisania wrażliwych plików lub tworzenia nowych plików w krytycznych lokalizacjach bezpieczeństwa, co stwarza poważne zagrożenie dla integralności systemu.
Recommendation
Zaleca się aktualizację biblioteki Compressing do wersji 1.10.4 lub 2.0.1, aby usunąć tę podatność.

- CVE-2026-92229Critical
The Forminator Forms plugin for WordPress (versions up to and including 1.57.2) is vulnerable to arbitrary shortcode execution. This is due to the software allowing users to execute an action that does not properly validate a value before running do_shortcode. This makes it possible for unauthenticated attackers to execute arbitrary shortcodes.
- CVE-2026-89274Critical
The WP Recipe Maker plugin for WordPress (versions up to and including 10.8.1) is vulnerable to arbitrary shortcode execution. The sanitize_metadata() function recursively calls do_shortcode() on recipe metadata fields, including reviewBody populated from comment content, without sanitizing shortcode tokens before execution. Unauthenticated attackers can execute arbitrary registered shortcodes on every recipe page render, disclosing data in JSON-LD metadata.
- CVE-2026-84434Critical
The Gravity Forms plugin for WordPress (versions up to and including 3.1.0.4) is vulnerable to arbitrary file upload via the upload_file function. A mismatch between validation and persistence pipelines allows hidden file upload fields to bypass extension validation. Unauthenticated attackers can upload executable files, enabling remote code execution.
- CVE-2026-93740Critical
A buffer overflow vulnerability was identified in the Totolink A3002MU (version Hh-B20211125.1046) within the formWlEncrypt function of the /boafrm/formWlEncrypt file. Manipulation of the submit-url argument allows remote exploitation. The exploit is publicly available and may be used.
- CVE-2026-93739Critical
A buffer overflow vulnerability was determined in the Totolink A3002MU (version Hh-B20211125.1046) within the formWlAc function of the /boafrm/formWlAc file. Manipulation of the submit-url argument can lead to a buffer overflow. The attack may be performed remotely, and the exploit has been publicly disclosed.
- CVE-2026-75885Critical
A flaw was found in the OpenShift console allowing unauthenticated access to the /api/devfile/ and /api/devfile/samples/ endpoints. A remote attacker can send crafted devfile payloads, leading to Server-Side Request Forgery (SSRF) and, by sending repeated large requests without a specified content length, to unbounded memory growth and Denial of Service (DoS).
- CVE-2026-93738Critical
A buffer overflow vulnerability was found in the Totolink A3002MU (version Hh-B20211125.1046) within the formSchedule function of the /boafrm/formSchedule file. Manipulation of the webpage argument results in a buffer overflow. The attack is possible remotely, and the exploit has been made public.
- CVE-2026-93839Critical
LightLLM through version 1.2.0 contains an authentication bypass vulnerability in the /pd_register WebSocket endpoint that allows unauthenticated attackers to register arbitrary nodes by supplying crafted JSON without peer address validation. Attackers can disclose full user prompts routed to their socket, trigger denial of service by replacing legitimate nodes, or make the PD Master issue requests to internal network addresses.
- CVE-2026-84082Critical
IBM Guardium Data Protection 12.2 could allow a remote attacker to execute arbitrary SQL commands due to improper neutralization of special elements used in an SQL command.
- CVE-2026-84078Critical
IBM Guardium Data Protection 12.2 is vulnerable to a missing authentication vulnerability in the LoadBalancerServlet. An unauthenticated user can access privileged load-balancer operations, potentially resulting in unauthorized actions and impact to the integrity and availability of the affected system.
Original NVD description (English source)
Compressing is a compressing and uncompressing lib for node. In version 2.0.0 and 1.10.3 and prior, Compressing extracts TAR archives while restoring symbolic links without validating their targets. By embedding symlinks that resolve outside the intended extraction directory, an attacker can cause subsequent file entries to be written to arbitrary locations on the host file system. Depending on the extractor’s handling of existing files, this behavior may allow overwriting sensitive files or creating new files in security-critical locations. This issue has been patched in versions 1.10.4 and 2.0.1.
