Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-5205 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- pow (Hex): affected all versions; fixed in 1.0.16\n- pow (Hex): affected all versions; fixed in 1.0.16\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-2020-5205/ (Markdown: https://insights.sbomify.com/CVE-2020-5205/index.md)","id":"CVE-2020-5205","markdown":"https://insights.sbomify.com/CVE-2020-5205/index.md","name":"CVE-2020-5205","record":{"aliases":["GHSA-v2wf-c3j6-wpvw"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":true,"product_category":"Elixir authentication library","requires_auth":"low_privilege","summary":"Attackers can hijack user sessions in Pow if a persistent session store like Redis is used instead of the default cookie store.","user_interaction":"required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"pow","vendor":"powauth"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:C/C:H/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-384","name":"Session Fixation"}],"description":"In Pow (Hex package) before 1.0.16, the use of Plug.Session in Pow.Plug.Session is susceptible to session fixation attacks if a persistent session store is used for Plug.Session, such as Redis or a database.
