eml_parser has parser DoS via deeply nested parentheses in e-mail headers

Summaryemlparser uses the email.utils.getaddresses function from the CPython standard library to parse e-mail headers that contain e-mail addresses such as To, Cc, Bcc, From, Reply-To, Sender, .... When the input header contains a deeply nested CFWS comment / folding white space construct, the...

eml_parser vulnerable to DoS via deeply nested parens in Received headers

Summaryemlparser strips parenthesised CFWS comments from Received: headers using a regex-based fix-point loop. The loop has quadratic time complexity in the number of nested parens. A single Received: header containing 5,000 nested parens causes 1.3 seconds of CPU saturation per parsed message;...

PYSEC-2026-3905 praisonaiagents has an SSRF protection bypass in `spider_tools._host_is_blocked()` via DNS-resolved hostnames (`127.0.0.1.nip.io`)

Summary praisonaiagents/tools/spidertools.py contains an SSRF protection bypass. The function hostisblocked validates URLs against a list of blocked IP literals and hostname aliases, but never performs DNS resolution. Any hostname that resolves to a private or loopback IP address — including publ...

django CMS: Plugin move endpoint allows cyclic reparenting (DoS)

SummaryThe moveplugin admin endpoint does not prevent a plugin from being reparented under itself or one of its own descendants. Doing so creates a cycle in the plugin tree, after which the recursive descendant/ancestor SQL queries loop without terminating, stalling the request worker...

NLTK TweetTokenizer vulnerable to denial of service through catastrophic regex backtracking

The URLS regular expression in nltk/tokenize/casual.py, compiled into TweetTokenizer.WORDRE and applied by TweetTokenizer.tokenize, contains a naked-domain branch whose domain-label prefix a-z0-9+?:.\-a-z0-9+ is unbounded. Input consisting of many alternating label separators can be partitioned i...

Accelerate path traversal and denial of service via sharded checkpoint weight_map entries

Hugging Face Accelerate through 1.14.0 contains a path traversal vulnerability in loadcheckpointinmodel and loadcheckpointanddispatch functions that fail to sanitize weightmap entries from sharded checkpoint indexes. Attackers can supply relative paths with ../ sequences or absolute paths to read...

PYSEC-2026-3865 MLflow AI Gateway permits SSRF through an unvalidated api_base

MLflow's AI Gateway accepts an authconfig.apibase value when creating a gateway secret mlflow/server/handlers.py, creategatewaysecret with no validation of scheme, host, or IP range; the value is stored verbatim. The gateway proxy endpoint mlflow/server/gatewayapi.py, rawproxy subsequently issues...

PYSEC-2026-3856 Keras model loading is vulnerable to denial of service through HDF5 shape bombs

A vulnerability in keras-team/keras versions 3.15.0 allows for a denial of service DoS attack when loading malicious .keras model files via the keras.models.loadmodel function. The H5IOStore.getitem method in keras/src/saving/savinglib.py does not validate the shape or size of datasets, leading t...

CVE-2026-87824

A flaw was found in zstd-jni. Attackers can exploit this by supplying oversized per-sample lengths to the Zstd.trainFromBufferDirect function, which fails to validate the samples buffer capacity. This allows for reading past buffer boundaries, leading to out-of-bounds memory access and ultimately...

vim: Vim: Denial of Service via out-of-bounds write in terminal handling

A flaw was found in Vim, an open-source command-line text editor. This vulnerability allows a program displaying output in a Vim terminal window to trigger an out-of-bounds write by sending a specific byte sequence. This can lead to a crash of the Vim application, resulting in a Denial of Service...

vim: Vim: Denial of Service via crafted spell file

A flaw was found in Vim, an open-source command-line text editor. A remote attacker could exploit this vulnerability by convincing a user to load a specially crafted spell file. This malicious file can trigger a stack out-of-bounds write, which corrupts the editor's memory and causes it to crash...
