Linux Distros Unpatched Vulnerability : CVE-2026-90776
The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - 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...
[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...

PYSEC-2026-3879 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...

Tornado: Urlencoded body parsing omits max_num_fields, so one request can stall the event loop
SummaryTornado parses application/x-www-form-urlencoded bodies with urllib.parse.parseqs and does not pass maxnumfields. A body made almost entirely of separators produces tens of millions of fields, and the parse happens on the event loop before the handler runs, so a single request stalls the...
