An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-40039 in the wild and no public exploit code.\n\nAffected product: Pachno. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-40039/ (Markdown: https://insights.sbomify.com/CVE-2026-40039/index.md)","id":"CVE-2026-40039","markdown":"https://insights.sbomify.com/CVE-2026-40039/index.md","name":"CVE-2026-40039","record":{"aliases":["GHSA-qx2h-p95p-57w8"],"analysis":{"component_type":"web_application","fix_type":"no_fix_stated","impacts":["account_takeover","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Pachno web application","requires_auth":"none","summary":"Attackers can redirect users to malicious sites via the return_to parameter, facilitating phishing and credential theft in Pachno.","user_interaction":"required","vuln_class":"open_redirect"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-305","name":"Authentication Bypass by Primary Weakness"}],"description":"Pachno 1.0.6 contains an open redirection vulnerability that allows attackers to redirect users to arbitrary external websites by manipulating the return_to parameter.
