EUVD-2026-97600

Open WebUI 0.11.0 before 0.11.4 compiles user-chosen grep patterns for its knowledge and chat file search tools with a regex engine that expands nested counted repetition unbounded at compile time and caches the result. Authenticated users can have the model call grepknowledgefiles with short...

CVE-2026-107297: Inefficient Algorithmic Complexity

msgpack5 is a msgpack v5 implementation for node.js and the browser. Prior to 6.1.0, the streaming decoder reparses an incomplete array or map from the beginning whenever another chunk arrives. A remote peer can split one valid MessagePack container across many small chunks, causing completed...

smol-toml: Quadratic-time parse() from parseKey rescanning to end of document on each key line

Summary parse has a quadratic-time path in parseKey, reachable on default options with ordinary valid input. For every key line and table-header line, parseKey dist/struct.js, lines 58 and 86 finds the dotted-key separator with ctx.s.indexOf'.', ctx.p, where ctx.s is the whole document. When a ke...

NPM: vm2: timeout Option Bypass via FinalizationRegistry Cleanup Callback (Unbounded Host Event-Loop Block)

vm2: timeout Option Bypass via FinalizationRegistry Cleanup Callback (Unbounded Host Event-Loop Block)

Vulnerability Summary vm2's VM timeout option is documented and relied upon as the mechanism that bounds how long sandboxed code may execute. In the current implementation, the timeout only wraps the single synchronous call to VMrun via doWithTimeout → this.runScriptscript in lib/vm.js. It does...

SUSE CVE-2026-102414

pbkdf2 through 3.1.6 re-hashes passwords longer than the digest's block size on every iteration in its JavaScript fallback lib/sync.js. A password longer than the block size 64 bytes, or 128 bytes for sha384 and sha512 is passed to HMAC as the key on every iteration, and HMAC hashes such keys in...

markdown-it linkify: true has two quadratic paths, so a few hundred KB of markdown blocks the event loop for tens of seconds

Summary Two independent quadratic paths in the linkify: true handling. Both are in markdown-it's own code rather than in linkify-it, which stays linear on both payloads. src/rulescore/linkify.ts calls arrayReplaceAt once per linkified text token, and that rebuilds the whole children array each...

AZL-105089 CVE-2026-102277 affecting package nodejs-nodemon 2.0.3-5

The brace-expansion library generates arbitrary strings containing a common prefix and suffix. Prior to 1.1.21, 2.1.7, 3.0.9, and 5.0.12, the expand function handles untrusted a,b-shaped patterns with many trailing closing braces by restarting its scan once for each trailing closing brace. The...

brace-expansion: DoS via unbounded intermediate arrays, bypassing the CVE-2026-14257 mitigation

A flaw was found in the brace-expansion library. The expand function does not apply maxLength when constructing comma-alternative intermediate arrays or padded sequences, allowing attacker-controlled input to exhaust memory or block the event loop, resulting in a denial of service. This issue is...

CVE-2026-93749

A flaw was found in source-map-js. This vulnerability allows a remote attacker to trigger a denial of service by providing malformed input. Specifically, by supplying extremely large offset line values in indexed source maps, the attacker can cause the service's event loop to block, making it...

GHSA-VJCV-9J33-WJ62 Duplicate Advisory: vm2: timeout Option Bypass via FinalizationRegistry Cleanup Callback (Unbounded Host Event-Loop Block)

Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-r4fx-v8hh-22mv. This link is maintained to preserve external references. Original Description vm2 before 3.11.7 affected versions = 3.11.6 does not enforce the VM timeout option on code executed outside the...

CVE-2026-92596

A flaw was found in Nodemailer's addressparser component. This vulnerability, due to quadratic time complexity, allows a remote attacker to cause a Denial of Service DoS. By sending a specially crafted email with a large, comma-separated list of addresses, the attacker can block the Node.js event...

Linux Distros Unpatched Vulnerability : CVE-2026-90776

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...
