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-2020-15128 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- october/rain (Packagist): affected from 1.0.319; fixed in 1.0.468\n- october/rain (Packagist): affected from 1.0.319; fixed in 1.0.468\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-2020-15128/ (Markdown: https://insights.sbomify.com/CVE-2020-15128/index.md)","id":"CVE-2020-15128","markdown":"https://insights.sbomify.com/CVE-2020-15128/index.md","name":"CVE-2020-15128","record":{"aliases":["GHSA-55mm-5399-7r63"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"OctoberCMS","requires_auth":"none","summary":"Attackers can bypass cookie validation by reusing encrypted values across different cookie names, potentially forcing decryption of sensitive data.","user_interaction":"required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"october","vendor":"octobercms"}],"cvss":{"score":6.1,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-327","name":"Use of a Broken or Risky Cryptographic Algorithm"},{"id":"CWE-565","name":"Reliance on Cookies without Validation and Integrity Checking"}],"description":"In OctoberCMS before version 1.0.468, encrypted cookie values were not tied to the name of the cookie the value belonged to. This meant that certain classes of attacks that took advantage of other theoretical vulnerabilities in user facing code (nothing exploitable in the core project itself) had a higher chance of succeeding. Specifically, if your usage exposed a way for users to provide unfiltered user input and have it returned to them as an encrypted cookie (ex. storing a user provided search query in a cookie) they could then use the generated cookie in place of other more tightly controlled cookies; or if your usage exposed the plaintext version of an encrypted cookie at any point to the user they could theoretically provide encrypted content from your application back to it as an encrypted cookie and force the framework to decrypt it for them.
