Summary
Grafana Image Renderer jest podatny na zdalne wykonanie kodu z powodu luki w zapisie plików. Luka ta wynika z braku walidacji parametru filePath w punkcie końcowym /render/csv, co pozwala atakującemu na zapisanie obiektu współdzielonego w dowolnej lokalizacji, która jest następnie ładowana przez proces Chromium.
Risk Assessment
Organizacje mogą być narażone na zdalne wykonanie kodu, jeśli domyślny token autoryzacyjny nie został zmieniony lub jest znany atakującemu, a także jeśli atakujący ma dostęp do punktu końcowego renderera obrazów.
Recommendation
Zaleca się zmianę domyślnego tokena autoryzacyjnego oraz ograniczenie dostępu do punktu końcowego renderera obrazów, aby zminimalizować ryzyko wykorzystania tej luki.

The HTTP Basic Authentication modules in ((OTRS)) Community Edition 6 and prior accept the authenticated username from either the REMOTE_USER or HTTP_REMOTE_USER environment variable. In CGI and mod_perl based deployments, HTTP request headers may be mapped to corresponding HTTP_* environment variables, so an unauthenticated remote attacker can supply a crafted Remote-User request header which is exposed to the application as HTTP_REMOTE_USER. When HTTP Basic Authentication is configured as the authentication backend, OTRS trusts this value as an already authenticated username and does not perform an additional password verification.
- CVE-2026-78357Critical
In OTRS, previously issued authentication tokens (JWT) are not immediately invalidated when an agent or customer user account is deactivated or its password is changed. A token may remain valid until its regular expiration time, approximately 16 hours. An attacker who previously obtained a valid token can continue to access OTRS with the privileges of the affected account.
- CVE-2026-108804Critical
A vulnerability was detected in TRENDnet TEW-751DR, TEW-752DRU and TEW733GR routers in versions 1.03B01/1.03B03, affecting the fwrite function in pigwidgeon.cgi of the Web Management Backend component. Manipulation of the service argument leads to OS command injection, and the attack can be launched remotely. The exploit is publicly available.
- CVE-2026-66086Critical
In the modem OTA stack, there is a possible stack-based buffer overflow due to improper validation of scheduling information in SIB1 messages. This could lead to remote code execution or denial of service with no additional execution privileges needed.
- CVE-2026-108860Critical
BotSharp through 5.2.0 contains an authentication bypass vulnerability that allows unauthenticated remote attackers to forge bearer tokens using the hard-coded Jwt:Key in WebStarter appsettings.json. Attackers can sign tokens with the committed HMAC secret and fixed botsharp issuer and audience to impersonate any known user, including administrators, on Authorize-protected API routes.
- CVE-2026-108753Critical
Agnaistic agnai through 1.0.555 contains a hard-coded credentials vulnerability in self-host.docker-compose.yml, which sets a fixed admin password and public JWT secret. Unauthenticated attackers can log in as admin or sign their own JWT with admin: true to impersonate users, reset passwords, and change server configuration.
- CVE-2026-108576Critical
A vulnerability was found in TOZED X300 up to 6.01.3. This vulnerability affects the function process_ping of the component IPPingDiagnostics Handler. The manipulation of the argument Host results in os command injection. The attack can be launched remotely. The vendor was contacted early about this disclosure but did not respond in any way.
- CVE-2026-86717Critical
The Insurify WordPress plugin through 1.0 does not have authorisation and nonce checks on one of its AJAX actions, allowing unauthenticated users to delete arbitrary WordPress options, which can take the site offline and strip every user of their role.
- CVE-2026-86706Critical
The Quick quotes WordPress plugin through 1.0.0 does not perform any capability or nonce check on one of its AJAX actions and lets the caller choose which option is written, allowing unauthenticated users to alter arbitrary site settings and to make the site unavailable.
- CVE-2026-85121Critical
The Insurify WordPress plugin through 1.0 does not have authorisation and nonce checks on one of its AJAX actions, allowing unauthenticated users to create and overwrite arbitrary WordPress options with request data, which can take the site offline and deactivate all of its Insurify WordPress plugin through 1.0.
Original NVD description (English source)
Grafana Image Renderer is vulnerable to remote code execution due to an arbitrary file write vulnerability. This is due to the fact that the /render/csv endpoint lacked validation of the filePath parameter that allowed an attacker to save a shared object to an arbitrary location that is then loaded by the Chromium process. Instances are vulnerable if: 1. The default token ("authToken") is not changed, or is known to the attacker. 2. The attacker can reach the image renderer endpoint. This issue affects grafana-image-renderer: from 1.0.0 through 4.0.16.
