LangChain is a framework for building agents and LLM-powered applications. Prior to 0.3.84 and 1.2.28, LangChain's f-string prompt-template validation was incomplete in two respects. First, some prompt template classes accepted f-string templates and formatted them without enforcing the same...

CVE-2026-40087

LangChain CVE-2026-40087 affects the f-string prompt-template validation prior to versions 0.3.84 and 1.2.28. The vulnerability arises because DictPromptTemplate and ImagePromptTemplate could accept templates containing attribute access or indexing expressions and evaluate them during formatting,...

Regular Expression Denial of Service (ReDoS)

Overview fast-jwt is a Fast JSON Web Token implementation Affected versions of this package are vulnerable to Regular Expression Denial of Service ReDoS via the allowedAud, allowedIss, allowedSub, allowedJti, or allowedNonce options when used with RegExp objects and RegExp is configured with nest...

minimatch: Minimatch: Denial of Service via catastrophic backtracking in glob expressions

A flaw was found in minimatch. A remote attacker could exploit this vulnerability by providing a specially crafted glob expression with nested unbounded quantifiers. This could lead to catastrophic backtracking in the V8 JavaScript engine, causing the application to become unresponsive and...

Regular Expression Denial of Service (ReDoS)

Overview addressable is an is an alternative implementation to the URI implementation that is part of Ruby's standard library. Affected versions of this package are vulnerable to Regular Expression Denial of Service ReDoS in the URI template matching due to the use of regular expressions with...

CVE-2026-34211

SandboxJS is a JavaScript sandboxing library. Prior to 0.8.36, the @nyariv/sandboxjs parser contains unbounded recursion in the restOfExp function and the lispify/lispifyExpr call chain. An attacker can crash any Node.js process that parses untrusted input by supplying deeply nested expressions...

go-ipld-prime: DAG-CBOR decoder unbounded memory allocation from CBOR headers

The DAG-CBOR decoder uses collection sizes declared in CBOR headers as Go preallocation hints for maps and lists. The decoder does not cap these size hints or account for their cost in its allocation budget, allowing small payloads to cause excessive memory allocation. A CBOR map or list header c...

GHSA-5JG4-P4QW-CGFR @stablelib/cbor: Stack exhaustion Denial of Service via deeply nested CBOR arrays, maps, or tags

Summary @stablelib/cbor decodes nested CBOR structures recursively and does not enforce a maximum nesting depth. A sufficiently deep attacker-controlled CBOR payload can therefore crash decoding with RangeError: Maximum call stack size exceeded. Details The decoder processes arrays, maps, and...
