An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-26138 exists.\n\nAffected product: drogonframework/drogon. 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-2023-26138/ (Markdown: https://insights.sbomify.com/CVE-2023-26138/index.md)","id":"CVE-2023-26138","markdown":"https://insights.sbomify.com/CVE-2023-26138/index.md","name":"CVE-2023-26138","record":{"aliases":["GHSA-3jvv-m32r-4hpf"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_modify","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"C++ web framework","requires_auth":"none","summary":"Attackers can inject CRLF characters into HTTP headers via the addHeader function, potentially manipulating request structure or bypassing security controls.","user_interaction":"required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"snyk","cpe":[{"product":"drogon","vendor":"drogon"}],"cvss":{"score":5.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N/E:P","version":"3.1"},"cwes":[{"id":"CWE-74","name":"Improper Neutralization of Special Elements in Output Used by a Downstream Component"},{"id":"CWE-93","name":"Improper Neutralization of CRLF Sequences"}],"description":"All versions of the package drogonframework/drogon are vulnerable to CRLF Injection when untrusted user input is used to set request headers in the addHeader function.
