CVE-2026-24129
HighSummary
Runtipi to oparty na Dockerze osobisty orchestrator serwerów domowych, który w wersjach 3.7.0 i wyższych pozwala uwierzytelnionemu użytkownikowi na wykonywanie dowolnych poleceń systemowych na serwerze hosta poprzez wstrzykiwanie metaznaków powłoki do nazw plików kopii zapasowych. BackupManager nie sanitizuje nazw plików przesyłanych kopii zapasowych, co umożliwia atakującemu umieszczenie pliku zawierającego metaznaki powłoki w przewidywalnej lokalizacji.
Risk Assessment
Wykorzystanie tej podatności może prowadzić do nieautoryzowanego dostępu do systemu oraz wykonania dowolnych poleceń, co stwarza poważne zagrożenie dla bezpieczeństwa organizacji.
Recommendation
Zaleca się aktualizację Runtipi do wersji 4.7.0 lub nowszej, aby usunąć tę podatność oraz wdrożenie dodatkowych środków zabezpieczających w celu monitorowania i ograniczenia dostępu do systemu.

OpenPanel js-runtime through commit bad75bdd contains a sandbox escape vulnerability in the JavaScript webhook template validator that fails to block computed member access to constructor chains. Attackers with project write access can create webhook templates using computed property notation to access Function constructor and execute arbitrary code in the worker process.

A vulnerability has been identified in the Totolink A3002MU router (version Hh-B20211125.1046) in the formWsc function of the /boafrm/formWsc file. Manipulation of the localPin argument leads to command injection. The attack can be launched remotely, and a public exploit is already available.
- CVE-2026-86591Critical
The Botiga Pro WordPress plugin before 1.6.5 does not perform any authorisation checks on one of its REST routes, allowing unauthenticated users to update arbitrary WordPress options with arbitrary values, which could lead to privilege escalation and a full site takeover. The same route also allows unauthenticated users to store arbitrary web scripts which are then executed on every page of the site's front end, as well as to move arbitrary posts to the trash.

A vulnerability has been discovered in the Totolink A3002MU router (version Hh-B20211125.1046) in the formWlWds function of the /boafrm/formWlWds file. Manipulation of the submit-url argument results in a buffer overflow. The attack can be launched remotely, and a public exploit has already been released.
- 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).
Original NVD description (English source)
Runtipi is a Docker-based, personal homeserver orchestrator that facilitates multiple services on a single server. Versions 3.7.0 and above allow an authenticated user to execute arbitrary system commands on the host server by injecting shell metacharacters into backup filenames. The BackupManager fails to sanitize the filenames of uploaded backups. The system persists user-uploaded files directly to the host filesystem using the raw originalname provided in the request. This allows an attacker to stage a file containing shell metacharacters (e.g., $(id).tar.gz) at a predictable path, which is later referenced during the restore process. The successful storage of the file is what allows the subsequent restore command to reference and execute it. This issue has been fixed in version 4.7.0.
