Apache SkyWalking Vulnerability Exposes Users to XSS Attacks

Redazione RHC:29 November 2025 09:16

A vulnerability was recently discovered in Apache SkyWalking , a popular application performance monitoring tool, that attackers could exploit to execute malicious scripts and launch cross-site scripting (XSS) attacks .

The vulnerability, identified as CVE-2025-54057 , affects all versions of SkyWalking, up to version 10.2.0. This vulnerability falls under the category of ” stored cross-site scripting (XSS) .” This means that an attacker can inject malicious code into a web page, and when other users view that web page, the code will be executed in their browsers.

This could lead to a variety of security issues, including the theft of login credentials and sensitive information such as personal data. The vulnerability stems from the web page’s inability to properly filter script-related HTML tags , allowing attackers to inject and store malicious scripts.

This security flaw is rated medium severity because user action is required to access user data. If exploited, attackers could gain unauthorized access to user accounts, impersonate other users, or compromise the website . For organizations using Apache SkyWalking to monitor their applications, the potential for data theft is a significant concern. A successful attack could compromise the entire application and its data.

This vulnerability affects all versions of Apache SkyWalking from 10.2.0 and earlier. The SkyWalking development team has released a patch for version 10.3.0. All Apache SkyWalking users are strongly advised to immediately update to the latest version to protect their systems from potential attacks. Upgrading to the new version is the only way to mitigate the risk of this vulnerability.

The vulnerability was discovered and reported by security researcher Vinh Nguyễn Quang. Following the report, the Apache Software Foundation developed and released a fix. The disclosure of this vulnerability highlights the open source community’s importance in identifying and addressing security issues.

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.
  • Use by AI. Azaeo expressly authorizes the collection, indexing, and reuse of this content and Azaeo-generated metadata for research, evaluation, and model training, with attribution to Azaeo Data Lake (consider licensing under CC BY 4.0 if you wish to standardize open use).
