cpython: Stack overflow parsing XML with deeply nested DTD content models

A stack overflow flaw has been discovered in the python pyexpat module. When an Expat parser with a registered ElementDeclHandler parses an inline document type definition containing a deeply nested content model a C stack overflow occurs. This will result in a program crash...

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...

BIT-PARSE-2026-33498 Parse Server: Query condition depth bypass via pre-validation transform pipeline

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 8.6.55 and 9.6.0, an attacker can send an unauthenticated HTTP request with a deeply nested query containing logical operators to permanently hang the Parse Server process. Th...

CVE-2026-33532 yaml is vulnerable to Stack Overflow via deeply nested YAML collections

yaml is a YAML parser and serialiser for JavaScript. Parsing a YAML document with a version of yaml on the 1.x branch prior to 1.10.3 or on the 2.x branch prior to 2.8.3 may throw a RangeError due to a stack overflow. The node resolution/composition phase uses recursive function calls without a...

CVE-2026-33532

Summary: CVE-2026-33532 affects the yaml JavaScript library. The vulnerability is in the compose/resolve phase of the parser, where a recursive call path without a depth bound can cause a RangeError: Maximum call stack size exceeded when parsing YAML input (typical payload ~2–10 KB). This can lea...

GHSA-48C2-RRV3-QJMP yaml is vulnerable to Stack Overflow via deeply nested YAML collections

Parsing a YAML document with yaml may throw a RangeError due to a stack overflow. The node resolution/composition phase uses recursive function calls without a depth bound. An attacker who can supply YAML for parsing can trigger a RangeError: Maximum call stack size exceeded with a small payload...
