CVE-2026-53550

A flaw was found in js-yaml, a JavaScript YAML parser and dumper. A remote attacker can exploit this vulnerability by providing a specially crafted YAML document that repeatedly uses the same alias in a merge sequence. This can lead to algorithmic CPU exhaustion, causing the Node.js worker or eve...

DEBIAN-CVE-2026-53550

js-yaml is a JavaScript YAML parser and dumper. Prior to 4.2.0, a crafted YAML document can trigger algorithmic CPU exhaustion in js-yaml merge-key processing by repeating the same alias many times in a merge sequence. This causes quadratic parse-time behavior relative to input size and can block...

CVE-2025-71379

vLLM versions = 0.6.3 and 0.9.0 contain multiple regular expression denial of service ReDoS vulnerabilities. Several regex patterns — in vllm/lora/utils.py, the phi4mini tool parser, and the OpenAI-compatible serving chat endpoint — are susceptible to catastrophic backtracking. An attacker...

CVE-2026-49293

CVE-2026-49293 affects js-toml up to v1.1.0. The parsing of hexadecimal/octal/binary integer literals uses a hand-written parseBigInt loop that multiplies the BigInt accumulator by the radix for every digit, yielding an O(n^2) time complexity in the length of the literal. A single TOML document c...
