FreeScout is a free help desk and shared inbox built with PHP's Laravel framework. Prior to version 1.8.223, an unauthenticated attacker can inject messages into any existing support conversation by sending a single email to the helpdesk's public address with a crafted `In-Reply-To` header. No credentials, tokens, or prior access are required. The injected message is rendered in the agent UI as a legitimate customer reply, the conversation is automatically reopened, and the `last_reply_from` field is set to the attacker's identity. Version 1.8.223 contains a fix.

CVE-2026-939645.3 MED19.9%
——6A vulnerability was detected in NginxProxyManager nginx-proxy-manager up to 2.15.1. This impacts the function internalCertificate.validate of the file backend/internal/certificate.js of the component Validate Route. The manipulation results in missing authentication. The attack can be launched remotely. The exploit is now public and may be used. Endpoint only processes and echoes back the certificate the caller submits (no stored data leaked); the real risk is unauthenticated openssl processing of attacker input. The project was informed of the problem early through an issue report but has not responded yet.1dCVE-2026-939604.3 MED30.4%
——9A vulnerability was identified in Pixelfed up to 0.12.11. Impacted is the function instancePeers of the file app/Http/Controllers/Api/ApiV1Controller.php of the component OAuth Scope Handler. Such manipulation of the argument ID leads to missing authentication. The attack may be performed from remote. The exploit is publicly available and might be used. Upgrading to version 0.12.10 is recommended to address this issue. The name of the patch is 68dca5097305fa0065d029587b2233524636025a. Upgrading the affected component is advised.1dCVE-2026-939845.3 MED10.7%
——3OpenPanel tracking API through commit bad75bddc74d12d36cfb843f4531d3b830a8d994 fails to verify client secret cryptographic hash before authorizing revenue events and bot filtering. Attackers with only a public client ID can supply arbitrary dummy secrets to inject forged revenue metrics and bypass bot detection filters.2dCVE-2026-890935.3 MED25.7%
——8The Better Messages – Chat Rooms, Group Chat, Private Messages & AI Chat Bots plugin for WordPress is vulnerable to Information Exposure by Spoofing in all versions up to, and including, 2.15.33. This is due to the `is_ai_bot_user()` function identifying privileged internal AI bot accounts by performing a prefix check for `'ai-chat-bot-'` against a guest record's stored IP address, which is populated verbatim from the client-controlled `X-Real-IP` request header during unauthenticated guest registration. This makes it possible for unauthenticated attackers to register a guest identity that the plugin treats as its own internal AI bot, bypassing the per-room role allowlist, draft-status check, and join filters — which are all short-circuited by the bot check in `user_can_join()` and `user_can_read()` — to join administrator-restricted chat rooms, post messages into them, and read the private message history of other users.2dCVE-2026-758789.1 CRÍ40.3%
