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...

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...

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...

CVE-2026-26209

A flaw was found in cbor2, a library for encoding and decoding Concise Binary Object Representation CBOR data. A remote attacker can exploit this vulnerability by sending a specially crafted CBOR payload containing deeply nested structures. This can cause the application to crash due to...

CVE-2026-26209

CVE-2026-26209

The CVE-2026-26209 issue affects the Python library cbor2 (including the C extension _cbor2) prior to version 5.9.0. The root cause is uncontrolled recursion when decoding deeply nested CBOR structures, as the C extension relies on Python’s Py_EnterRecursiveCall rather than a data-driven depth li...

Overview parse-server is a version of the Parse backend that can be deployed to any infrastructure that can run Node.js. Affected versions of this package are vulnerable to Uncontrolled Recursion via the pre-validation transform pipeline. An attacker can cause the server process to become...

GHSA-9FJP-Q3C4-6W3J Parse Server has a query condition depth bypass via pre-validation transform pipeline

Impact An attacker can send an unauthenticated HTTP request with a deeply nested query containing logical operators to permanently hang the Parse Server process. The server becomes completely unresponsive and must be manually restarted. This is a bypass of the fix for CVE-2026-32944. Patches The...
