NLTK version 3.9.4 is vulnerable to a path traversal attack due to an incomplete fix for GitHub Issue 3504. The UNSAFE NO PROTOCOL RE regex in nltk/data.py checks for literal ../ sequences but fails to account for percent-encoded traversal sequences such as ..%2f. The url2pathname function decode...

Cross-site Scripting (XSS)

Overview secureheaders is a library that manages application of security headers with many safe defaults. Affected versions of this package are vulnerable to Cross-site Scripting XSS via the overridecontentsecuritypolicydirectives process. An attacker can inject arbitrary Content Security Policy...

PYSEC-2026-439 ormar is vulnerable to SQL Injection through aggregate functions min() and max()

Report of SQL Injection Vulnerability in Ormar ORM A SQL Injection attack can be achieved by passing a crafted string to the min or max aggregate functions. Brief description When performing aggregate queries, Ormar ORM constructs SQL expressions by passing user-supplied column names directly int...

PYSEC-2026-383 Langroid has WAF Bypass Leading to RCE in TableChatAgent

Affected Scope langroid = 0.59.31 Vulnerability Description CVE-2025-46724 fix bypass: TableChatAgent can call pandaseval tool to evaluate the expression. There is a WAF in langroid/utils/pandasutils.py introduced to block code injection CVE-2025-46724. However it can be bypassed due to literalok...

EPyT-Flow vulnerable to unsafe JSON deserialization (__type__)

ImpactEPyT-Flow’s REST API parses attacker-controlled JSON request bodies using a custom deserializer myloadfromjson that supports a type field. When type is present, the deserializer dynamically imports an attacker-specified module/class and instantiates it with attacker-supplied arguments. This...

PraisonAI Vulnerable to Remote Code Execution via YAML Deserialization in Agent Definition Loading

SummaryThe AgentService.loadAgentFromFile method uses the js-yaml library to parse YAML files without disabling dangerous tags such as !!js/function and !!js/undefined. This allows an attacker to craft a malicious YAML file that, when parsed, executes arbitrary JavaScript code. An attacker can...

Summary The AgentService.loadAgentFromFile method uses the js-yaml library to parse YAML files without disabling dangerous tags such as !!js/function and !!js/undefined. This allows an attacker to craft a malicious YAML file that, when parsed, executes arbitrary JavaScript code. An attacker can...

Pipecat: Remote Code Execution by Pickle Deserialization Through LivekitFrameSerializer

Remote Code Execution via Unsafe Deserialization in Pipecat's LivekitFrameSerializer SummaryA critical vulnerability exists in Pipecat's LivekitFrameSerializer – an optional, non-default, undocumented frame serializer class now deprecated intended for LiveKit integration. The class's deserialize...

PYSEC-2026-530 SciTokens is vulnerable to SQL Injection in KeyCache

Summary The KeyCache class in scitokens was vulnerable to SQL Injection because it used Python's str.format to construct SQL queries with user-supplied data such as issuer and keyid. This allowed an attacker to execute arbitrary SQL commands against the local SQLite database. Ran the POC below...

PickleScan's pkgutil.resolve_name has a universal blocklist bypass

Summarypkgutil.resolvename is a Python stdlib function that resolves any "module:attribute" string to the corresponding Python object at runtime. By using pkgutil.resolvename as the first REDUCE call in a pickle, an attacker can obtain a reference to ANY blocked function e.g., os.system,...

litellm vulnerable to remote code execution based on using eval unsafely

BerriAI/litellm version v1.35.8 contains a vulnerability where an attacker can achieve remote code execution. The vulnerability exists in the adddeployment function, which decodes and decrypts environment variables from base64 and assigns them to os.environ. An attacker can exploit this by sendin...

pgAdmin 4 vulnerable to Unsafe Deserialization and Remote Code Execution by an Authenticated user

pgAdmin prior to version 8.4 is affected by a path-traversal vulnerability while deserializing users’ sessions in the session handling code. If the server is running on Windows, an unauthenticated attacker can load and deserialize remote pickle objects and gain code execution. If the server is...
