Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-35459 exists.\n\nAffected packages and fixed versions:\n- pyload-ng (PyPI): affected all versions up to 0.5.0b3.dev96; no fix listed\n- pyload-ng (PyPI): affected all versions up to 0.5.0b3.dev96; no fix listed\n- pyload-ng (PyPI): affected all versions up to 0.5.0b3.dev96; no fix listed\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-2026-35459/ (Markdown: https://insights.sbomify.com/CVE-2026-35459/index.md)","id":"CVE-2026-35459","markdown":"https://insights.sbomify.com/CVE-2026-35459/index.md","name":"CVE-2026-35459","record":{"aliases":["GHSA-7gvf-3w72-p2pg","PYSEC-2026-495"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"pyLoad download manager","requires_auth":"low_privilege","summary":"Authenticated users can bypass SSRF protections in pyLoad by using HTTP redirects to access internal network resources.","user_interaction":"not_required","vuln_class":"ssrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"pyload-ng","vendor":"pyload-ng_project"}],"cvss":{"score":9.3,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:N/SC:H/SI:H/SA:N","version":"4.0"},"cwes":[{"id":"CWE-918","name":"Server-Side Request Forgery"}],"description":"pyLoad is a free and open-source download manager written in Python. In 0.5.0b3.dev96 and earlier, pyLoad has a server-side request forgery (SSRF) vulnerability. The fix for CVE-2026-33992 added IP validation to BaseDownloader.download() that checks the hostname of the initial download URL. However, pycurl is configured with FOLLOWLOCATION=1 and MAXREDIRS=10, causing it to automatically follow HTTP redirects. Redirect targets are never validated against the SSRF filter. An authenticated user with ADD permission can bypass the SSRF fix by submitting a URL that redirects to an internal address.","ecosystems":["PyPI"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"pyLoad has SSRF fix bypass via HTTP redirect","id":"CVE-2026-35459","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"ssrf","year":"2026"},"n_packages":3,"n_references":2,"next":{"headline":"Papra has an HTML Injection in Transactional Emails via Unescaped User Display Name","id":"CVE-2026-35460"},"packages":[{"ecosystem":"PyPI","fixed":[],"introduced":["0"],"last_affected":["0.5.0b3.dev96"],"package":"pyload-ng","purl":null,"source":"GHSA-7gvf-3w72-p2pg"},{"ecosystem":"PyPI","fixed":[],"introduced":["0"],"last_affected":["0.5.0b3.dev96"],"package":"pyload-ng","purl":"pkg:pypi/pyload-ng","source":"GHSA-7gvf-3w72-p2pg"},{"ecosystem":"PyPI","fixed":[],"introduced":["0"],"last_affected":["0.5.0b3.dev96"],"package":"pyload-ng","purl":"pkg:pypi/pyload-ng","source":"PYSEC-2026-495"}],"prev":{"headline":"Gotenberg has a ReDoS via extraHttpHeaders scope feature","id":"CVE-2026-35458"},"products":["pyload"],"published":"2026-04-06","related":[{"cvss_score":9.8,"headline":"pyLoad CNL Blueprint is vulnerable to Path Traversal through `dlc_path` leading to Remote Code Execution (RCE)","id":"CVE-2025-54802","kev_date_added":null,"published":"2025-08-05"},{"cvss_score":9.7,"headline":"Cross-Site Request Forgery on any API call in pyLoad may lead to admin privilege escalation","id":"CVE-2024-22416","kev_date_added":null,"published":"2024-01-17"},{"cvss_score":9.6,"headline":"Cross-site Scripting (XSS) - Stored in pyload/pyload","id":"CVE-2023-0488","kev_date_added":null,"published":"2023-01-26"},{"cvss_score":8.8,"headline":"pyLoad has Improper Neutralization of Special Elements used in an OS Command","id":"CVE-2026-35463","kev_date_added":null,"published":"2026-04-07"},{"cvss_score":8.8,"headline":"pyload-ng: Authentication Bypass via Host Header Injection in ClickNLoad","id":"CVE-2026-33511","kev_date_added":null,"published":"2026-03-24"},{"cvss_score":8.3,"headline":"pyload-ng: non-admin SETTINGS users can redirect all outbound traffic through an attacker-controlled proxy","id":"CVE-2026-42313","kev_date_added":null,"published":"2026-05-11"}],"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":"CC BY 4.0","name":"PyPA Advisory Database","prefix":"PYSEC"},{"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)"}],"ssvc":{"automatable":"yes","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-04-07","vendors":["pyload"]},"summary":"Authenticated users can bypass SSRF protections in pyLoad by using HTTP redirects to access internal network resources.","url":"https://insights.sbomify.com/CVE-2026-35459/"}
