It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-64745 exists.\n\nAffected packages and fixed versions:\n- astro (npm): affected from 5.2.0; fixed in 5.15.6\n- astro (npm): affected from 5.2.0; fixed in 5.15.6\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2025-64745/ (Markdown: https://insights.sbomify.com/CVE-2025-64745/index.md)","id":"CVE-2025-64745","markdown":"https://insights.sbomify.com/CVE-2025-64745/index.md","name":"CVE-2025-64745","record":{"aliases":["GHSA-w2vj-39qv-7vh7"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Astro web framework","requires_auth":"none","summary":"Attackers can execute arbitrary JavaScript in developer browsers via malicious URLs in Astro's development server error pages when trailingSlash is enabled.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"astro","vendor":"astro"}],"cvss":{"score":2.7,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:C/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Astro is a web framework. Starting in version 5.2.0 and prior to version 5.15.6, a Reflected Cross-Site Scripting (XSS) vulnerability exists in Astro's development server error pages when the `trailingSlash` configuration option is used. An attacker can inject arbitrary JavaScript code that executes in the victim's browser context by crafting a malicious URL. While this vulnerability only affects the development server and not production builds, it could be exploited to compromise developer environments through social engineering or malicious links.
