When mail_max_userip_connections is set (defaul\nt 10) and reached, submission-login can crash with epoll() panic caused by file descriptor handling issues.\n\nRisk:\nIf running in high-security mode (default for community releases), only the new submission connection gets terminated. \nIf running in high-performance mode (default for Pr\no releases), all connections handled by the submission-login process will be terminated. The crashes can cause failure \nfor user to send a message, or it can cause duplica\nte messages to be sent. If TLS is not used (in the backend server processing the submission), duplicate deliveries \ncannot happen, because the crash can only happen at AUT\nH stage. No publicly available exploits are known.\n\nSolution:\nLimit the number of connections handled by single submission-login process. This has a performance impact though. \nUpdate to non-vulnerable version.\n\n\n\n---\n\n\n\nInternal reference: DOV-8874\nType: CWE-400 (Uncontrolled Resource Consumption)\nComponent: core\nReport confidence: Confirmed\nSolution status: Fixed by vendor\nAffected versions: OX Dovecot Pro core \u003e=2.3.0 \u003c3.0.7, OX Dovecot Pro core \u003e=3.1.0 \u003c3.1.6, OX Dovecot CE core \u003e=2.3.0 \n\u003c2.4.5\nFirst fixed revision: OX Dovecot Pro core 3.0.7, OX Dovecot Pro core 3.1.6, OX Dovecot CE core 2.4.5\nDiscovery date: 2026-03-11\nSolution date: 2026-08-26\nDisclosure date: 2026-08-26\nResearcher credits: ylwango613@yeswehack\nCVE: CVE-2026-33607\nCVSS: 4.3 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L)\n\nDetails:\nDovecot IMAP LIST match_sub() Exponential Backtracking \u2014 CPU Denial of Service.

          "value": "theshit is a command-line utility that automatically detects and fixes common mistakes in shell commands. Prior to version 0.1.1, the application loads custom Python rules and configuration files from user-writable locations (e.g., `~/.config/theshit/`) without validating ownership or permissions when executed with elevated privileges. If the tool is invoked with `sudo` or otherwise runs with an effective UID of root, it continues to trust configuration files originating from the unprivileged user\u0027s environment. This allows a local attacker to inject arbitrary Python code via a malicious rule or configuration file, which is then executed with root privileges. Any system where this tool is executed with elevated privileges is affected. In environments where the tool is permitted to run via `sudo` without a password (`NOPASSWD`), a local unprivileged user can escalate privileges to root without additional interaction. The issue has been fixed in version 0.1.1. The patch introduces strict ownership and permission checks for all configuration files and custom rules. The application now enforces that rules are only loaded if they are owned by the effective user executing the tool. When executed with elevated privileges (`EUID=0`), the application refuses to load any files that are not owned by root or that are writable by non-root users. When executed as a non-root user, it similarly refuses to load rules owned by other users. This prevents both vertical and horizontal privilege escalation via execution of untrusted code. If upgrading is not possible, users should avoid executing the application with `sudo` or as the root user. As a temporary mitigation, ensure that directories containing custom rules and configuration files are owned by root and are not writable by non-root users. Administrators may also audit existing custom rules before running the tool with elevated privileges."

          "value": "LibreChat is a ChatGPT clone with additional features. Version 0.8.1-rc2 does not enforce proper access control when\nquerying agent permissions. An authenticated attacker can read the permissions of arbitrary agents, even if they have no permissions for this agent. LibreChat allows the configuration of agents that have a predefined set of instructions and context. Private agents are not visible to other users. However, if an attacker knows the agent ID, they can read the permissions of the agent including the permissions individually assigned to other users. This issue is fixed in version 0.8.2-rc2."
