CVE-2026-44795 Spinnaker: Non-safe yaml deserialization allowing RCE when using specific types

Spinnaker is an open source, multi-cloud continuous delivery platform. Prior to 2026.1.0, 2026.0.3, 2025.4.4, and 2025.3.3, unsafe YAML processing bypasses safe deserialization when using CloudFormation deployments or CloudFoundry baking. The use of a non-safe constructor allows arbitrary loading...

CVE-2026-59868

js-yaml is a JavaScript YAML parser and dumper. From 5.0.0 before 5.2.0, when merge keys are enabled, js-yaml can spend quadratic CPU time parsing a document whose size grows only linearly when a chain of mappings uses merge keys where each mapping merges the previous one. This issue is fixed in...

OPENSUSE-SU-2026:21251-1 Security update for alloy

This update for alloy fixes the following issues: Update to version 1.17.0. Security issues fixed: - CVE-2026-25680: golang.org/x/net/html: parsing arbitrary HTML can consume excessive CPU time, possibly leading to denial of service bsc1267185. - CVE-2026-25681: golang.org/x/net/html: parsing...

js-yaml: js-yaml: Denial of Service via quadratic CPU time parsing with merge keys

A flaw was found in js-yaml, a JavaScript YAML parser and dumper. When merge keys are enabled, a remote attacker could exploit this vulnerability by crafting a YAML document where a chain of mappings uses merge keys, each merging the previous one. This can lead to a significant increase in CPU ti...

GHSA-4QPC-3HR4-R2P4 Symfony's YAML Parser Vulnerable to Exponential Memory Allocation via Recursive Collection-Alias Expansion ("Billion Laughs")

Description Symfony\Component\Yaml\Parser resolves YAML aliases anchor during parsing. Aliases that reference collections arrays, stdClass, TaggedValue-wrapped collections can themselves point to other collections containing aliases, creating exponential expansion at resolution time. A small inpu...

GHSA-C2P3-7M5P-CV8X Symfony hardened the parser when handling untrusted input

Description Symfony\Component\Yaml\Parser is the entry point for parsing YAML strings into PHP values via Yaml::parse. When the parser is exposed to attacker-controlled input, deeply nested mappings or sequences cause both the block-level Parser::parseBlock and inline Inline::parseSequence /...

Astra Linux – Vulnerability in snakeyaml

Using snakeYAML to parse untrusted YAML files may be vulnerable to Denial of Service attacks DOS. If the parser is running on user-supplied input, an attacker may provide content that causes the parser to crash due to a stack overflow...
