CVE-2026-90776
A flaw was found in Nodemailer's addressparser component. A remote attacker can exploit this by crafting malicious email headers containing specially formatted comments. This can lead to excessive CPU consumption and block the Node.js event loop, resulting in a denial of service for the applicati...
EUVD-2026-77000
Nodemailer versions 9.1.0 through 10.0.4 contain a quadratic time complexity vulnerability in the addressparser component when parsing email addresses with RFC 5322 comments. Attackers can craft malicious email headers with comment-separated atoms to consume excessive CPU and block the Node.js...

[SECURITY] Fedora 45 Update: libevent-2.1.13-1.fc45
The libevent API provides a mechanism to execute a callback function when a specific event occurs on a file descriptor or after a timeout has been reached. libevent is meant to replace the asynchronous event loop found in event driven network servers. An application just needs to call eventdispat...
CVE-2026-89752
A race condition in the Linux kernel's memory cgroup (memcg) subsystem can cause an indefinite reclaim loop when two open files concurrently update memory.max or memory.high. Because kernfs serializes operations only per open file, a first writer may continue reclaiming toward a stale target afte...

brace-expansion: Brace-expansion: Denial of Service due to exponential-time complexity
A flaw was found in brace-expansion. An attacker can exploit a vulnerability in the expand function by providing a specially crafted string. This string, containing consecutive non-expanding brace groups, can trigger exponential-time complexity, leading to significant CPU consumption and event-lo...

Open WebUI: Unauthenticated requests can stall the server via uncached OIDC fetches in back-channel logout
Summary The OIDC back-channel logout endpoint is unauthenticated by design, because the identity provider calls it without a browser session. Before checking whether the submitted logout token was genuine, the handler fetched the provider's discovery document and its signing keys over the network...

The version of the Tornado Python package installed on the remote host is prior to 6.5.8. It is, therefore, affected by a denial of service vulnerability: - Tornado is a Python web framework and asynchronous networking library. Prior to 6.5.8, Tornado parses application/x-www-form-urlencoded...
Open WebUI: Any authenticated user can hang the server via message deletion in a cyclic chat tree
Summary Chat histories are stored as an unvalidated JSON object. After a message is deleted, the code that picks the chat's new current message walked down the childrenIds links without recording where it had already been. Any account with the default user role could store a chat whose messages...

GHSA-JQHH-CJMQ-VMV6 Open WebUI: Any authenticated user can hang the server via a cyclic chat message history
Summary Chat histories are stored as an unvalidated JSON object. The walk that reconstructs a chat's message chain detected repeats using each message's own id field while moving through the history by map key, so a message that simply omitted id was never recorded as visited. A history whose...
