CVE-2026-82187

Ajenti is a Linux & BSD modular server admin panel. Prior to version 2.2.16, any authenticated user can call /api/core/tasks/start to enqueue InstallPlugin, UnInstallPlugin, or UpgradeAll from plugins/plugins/tasks.py without plugin-management authorization. InstallPlugin and UnInstallPlugin construct a pip package specification from unvalidated name and version fields, and the task worker invokes pip while running as root. A low-privileged user can therefore select or manipulate a package installed with root privileges and can install, remove, or upgrade plugins without administrative permission, resulting in root code execution and full host compromise. This issue is fixed in version 2.2.16.

Fluent Bit is a fast and lightweight logs, metrics, and traces processor for Linux, BSD, macOS, and Windows. From 0.11.0 until 5.0.8, plugins/out_forward/forward.c secure_forward_pong copies the server-controlled PONG[2] reason into the 32-byte stack buffer msg with memcpy without checking its MessagePack type or length. An attacker who controls or can impersonate an out_forward Secure Forward destination configured with Shared_Key or Empty_Shared_Key can send an oversized reason during the first handshake and overwrite stack control data. Protected builds reliably terminate, while builds without a stack canary or with a disclosure can allow remote code execution as the Fluent Bit process user. When the opt-in --supervisor mode is used, fork-only respawns preserve the canary and address layout, allowing repeated crash-or-survive probes to support code execution on a hardened build; ordinary exec-based or service-manager restarts do not preserve that state. This issue is fixed in version 5.0.8.

Mailu is a mail server distributed as a set of Docker images. From Mailu 2.0 until 2024.06.55 and prior to Mailu helm-charts 2.7.3, deployments with PROXY_AUTH_WHITELIST configured but REAL_IP_HEADER unset trusted a client-controlled X-Forwarded-By header for header-based proxy authentication. The proxy_hide_header directive in the nginx template at core/nginx/conf/proxy.conf hid the header from upstream responses but did not overwrite the incoming request value in this configuration. An unauthenticated remote attacker could therefore spoof the trusted proxy identity and bypass authentication. This issue is fixed in Mailu 2024.06.55 and Mailu helm-charts 2.7.3.

The fix for CVE-2026-47065/ZDRES-232 ("resolveProxyClass Not Overridden - acceptMatchers Filter Bypass via java.lang.reflect.Proxy"), released on 2026-06-02 and announced as "Fully addressed" in MINA 2.2.8, 2.1.13 and 2.0.29, was committed to the 2.2.X branch only. The 2.0.X and 2.1.X maintenance branches never received the resolveProxyClass() override, so the 2.0.29 and 2.1.13 artifacts listed as fixed -- and every later release on those lines, up to and including the current 2.0.30 and 2.1.14 -- remain vulnerable to the exact allow-list bypass that CVE-2026-47065 was meant to close.

A vulnerability in Open VSX allows an unauthenticated attacker to poison the per-extension metadata cache by supplying a crafted X-Forwarded-Host header, replacing download, signature, and public-key URLs with attacker-controlled ones. The cache keys do not include the host, so poisoned entries are served to all clients for the entry's lifetime (1 hour by default, cluster-wide with Redis).

A security vulnerability has been detected in Netcore NBR200V2 1.3.241127.071246. The affected function is vlan_load_form_uci in /usr/bin/routerd, where manipulation of the wan_num argument leads to buffer overflow. The attack can be initiated remotely and the exploit is publicly disclosed.

A weakness has been identified in Netcore NBR200V2 1.3.241127.071246. The affected function is wan_config_set_vlan in /usr/bin/routerd, where manipulation of the vlan_wanX.ports argument leads to buffer overflow. The attack can be performed remotely and the exploit is publicly available.

A security flaw has been discovered in Netcore NBR200V2 1.3.241127.071246. The issue affects the restore.cgi file in the Backup Restore component, where manipulation of the QUERY_STRING argument results in command injection. The attack can be carried out remotely and the exploit is publicly released.

A vulnerability was identified in Netcore NBR200V2 1.3.241127.071246. The vulnerability affects the /www/cgi-bin/upgrade file in the Firmware Upgrade CGI Endpoint component, where manipulation of the QUERY_STRING argument leads to command injection. The attack can be executed remotely and the exploit is publicly available.

A vulnerability was determined in Netcore NBR200V2 1.3.241127.071246. The vulnerability affects the /www/cgi-bin/network_tools file in the CGI Diagnostic Endpoint component, where manipulation of the param/key/val arguments causes command injection. Remote exploitation is possible and the exploit has been publicly disclosed.
