An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-54793 exists.\n\nAffected packages and fixed versions:\n- astro (npm): affected from 5.2.0; fixed in 5.12.8\n- astro (npm): affected from 5.2.0; fixed in 5.12.8\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-2025-54793/ (Markdown: https://insights.sbomify.com/CVE-2025-54793/index.md)","id":"CVE-2025-54793","markdown":"https://insights.sbomify.com/CVE-2025-54793/index.md","name":"CVE-2025-54793","record":{"aliases":["GHSA-cq8c-xv66-36gw"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"Astro web framework","requires_auth":"none","summary":"Attackers can redirect users to malicious external domains via crafted URLs in Astro SSR sites, facilitating phishing attacks.","user_interaction":"not_required","vuln_class":"open_redirect"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"astro","vendor":"astro"}],"cvss":{"score":5.5,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N/E:P","version":"4.0"},"cwes":[{"id":"CWE-601","name":"URL Redirection to Untrusted Site"}],"description":"Astro is a web framework for content-driven websites. In versions 5.2.0 through 5.12.7, there is an Open Redirect vulnerability in the trailing slash redirection logic when handling paths with double slashes. This allows an attacker to redirect users to arbitrary external domains by crafting URLs such as https://mydomain.com//malicious-site.com/. This increases the risk of phishing and other social engineering attacks. This affects sites that use on-demand rendering (SSR) with the Node or Cloudflare adapters. It does not affect static sites, or sites deployed to Netlify or Vercel. This issue is fixed in version 5.12.8. To work around this issue at the network level, block outgoing redirect responses with a Location header value that starts with `//`.","ecosystems":["npm"],"exploits":{"exploitdb":0,"first_seen":"2025-10-11","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":1,"refs":[{"date":"2025-10-11T04:23:20Z","kind":"github_poc","ref":"https://github.com/bhuvi-labs/ict279-cve-2025-54793","stars":0,"title":"Group project — CVE-2025-54793 detection \u0026 mitigation (Bhuvanesh, Shiva, Emma)"},{"date":null,"kind":"nuclei","ref":"http/cves/2025/CVE-2025-54793.yaml","stars":null,"title":"Astro SSR - Open Redirect"}],"tier":"weaponised"},"has_fix":true,"headline":"Astro: Duplicate trailing slash feature can lead to Open Redirects","id":"CVE-2025-54793","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"open_redirect","year":"2025"},"n_packages":2,"n_references":2,"next":{"headline":"Claude Code Research Preview has a Path Restriction Bypass which could allow unauthorized file access","id":"CVE-2025-54794"},"packages":[{"ecosystem":"npm","fixed":["5.12.8"],"introduced":["5.2.0"],"last_affected":[],"package":"astro","purl":null,"source":"GHSA-cq8c-xv66-36gw"},{"ecosystem":"npm","fixed":["5.12.8"],"introduced":["5.2.0"],"last_affected":[],"package":"astro","purl":"pkg:npm/astro","source":"GHSA-cq8c-xv66-36gw"}],"prev":{"headline":"LocalSend is Vulnerable to Man-in-the-Middle Attacks, Leading to File Interception","id":"CVE-2025-54792"},"products":["astro"],"published":"2025-08-08","related":[{"cvss_score":7.8,"headline":"Server source code is exposed to the public if sourcemaps are enabled","id":"CVE-2024-56159","kev_date_added":null,"published":"2024-12-19"},{"cvss_score":7.5,"headline":"Astro: Host header SSRF in prerendered error page fetch","id":"CVE-2026-54299","kev_date_added":null,"published":"2026-06-22"},{"cvss_score":7.2,"headline":"astro allows bypass of image proxy domain validation leading to SSRF and potential XSS","id":"CVE-2025-59837","kev_date_added":null,"published":"2025-10-28"},{"cvss_score":7.1,"headline":"Astro: Reflected XSS via unescaped slot name","id":"CVE-2026-50146","kev_date_added":null,"published":"2026-06-22"},{"cvss_score":7.1,"headline":"Astro is vulnerable to Reflected XSS via the server islands feature","id":"CVE-2025-64764","kev_date_added":null,"published":"2025-11-19"},{"cvss_score":6.9,"headline":"Astro middleware authentication checks based on url.pathname can be bypassed via url encoded values","id":"CVE-2025-64765","kev_date_added":null,"published":"2025-11-19"},{"cvss_score":6.9,"headline":"Unauthorized third-party images in Astro’s _image endpoint","id":"CVE-2025-55303","kev_date_added":null,"published":"2025-08-19"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"attribution","licence":"MIT","name":"Nuclei templates"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"yes","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-08-08","vendors":["withastro"]},"summary":"Attackers can redirect users to malicious external domains via crafted URLs in Astro SSR sites, facilitating phishing attacks.","url":"https://insights.sbomify.com/CVE-2025-54793/"}
