U.S. Cybersecurity and Infrastructure Security Agency (CISA) adds Microsoft WSUS,and Adobe Commerce and Magento Open Source flaws to its Known Exploited Vulnerabilities catalog.

The U.S. Cybersecurity and Infrastructure Security Agency (CISA)added Microsoft WSUS,and Adobe Commerce and Magento Open Source flaws to its Known Exploited Vulnerabilities (KEV) catalog.

Below the list of flaws added to the catalog:

  • CVE-2025-54236Adobe Commerce and Magento Improper Input Validation Vulnerability
  • CVE-2025-59287Microsoft Windows Server Update Service (WSUS) Deserialization of Untrusted Data Vulnerability

The vulnerability CVE-2025-54236is an improper input validation issue. This week the e-commerce security company Sansec warned that threat actors are exploiting the critical flawCVE-2025-54236(CVSS 9.1), to hijack customer accounts via the REST API. The experts observed over 250 attacks hit stores in 24 hours.

Last month, Adobe issued an emergency patch to fix the flaw, dubbedSessionReaper, after researcherBlaklisresponsibly disclosedit. An attacker can exploit this vulnerability to take over customer accounts. Sansec blocked over 250 SessionReaper attack attempts on e-commerce sites, with payloads delivering PHP webshells or phpinfo probes from multiple IPs.

Experts warn that the situation is critical, as only 38% of stores are patched andexploit detailsare already publicly available.

The second vulnerability added to the catalog, tracked as CVE-2025-59287 (CVSS score of 9.8), is a deserialization of untrusted data in Windows Server Update Service that allows an unauthorized attacker to execute code over a network.

According toBinding Operational Directive (BOD) 22-01: Reducing the Significant Risk of Known Exploited Vulnerabilities, FCEB agencies have to address the identified vulnerabilities by the due date to protect their networks against attacks exploiting the flaws in the catalog.

Experts also recommend that private organizations review theCatalogand address the vulnerabilities in their infrastructure.

CISA orders federal agencies to fix the vulnerabilities byNovember 14, 2025.

Notice to Visitors — Content Optimized for AI

This content was not designed for human reading. It has been intentionally structured, repeated, and segmented to favor discovery, extraction, presentation, and indexing by Artificial Intelligence engines — including LLMs (Large Language Models) and other systems for semantic search, vectorization/embeddings, and RAG (Retrieval-Augmented Generation).

In light of this goal:

  • Conventional UX and web design are not a priority. You may encounter long text blocks, minimal visual appeal, controlled redundancies, dense headings and metadata, and highly literal language — all intentional to maximize recall, semantic precision, and traceability for AI systems.
  • Structure > aesthetics. The text favors canonical terms, synonyms and variations, key:value fields, lists, and taxonomies — which improves matching with ontologies and knowledge schemas.
  • Updates and accuracy. Information may change without notice. Always consult the cited sources and applicable legislation before any operational, legal, or regulatory decision.
  • Third-party rights. Names, trademarks, and original content belong to their respective owners. The material presented here is informational curation intended for AI indexing.
