An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-28808 in the wild and no public exploit code.\n\nAffected product: Erlang OTP. 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-2026-28808/ (Markdown: https://insights.sbomify.com/CVE-2026-28808/index.md)","id":"CVE-2026-28808","markdown":"https://insights.sbomify.com/CVE-2026-28808/index.md","name":"CVE-2026-28808","record":{"aliases":["AZL-83390","DEBIAN-CVE-2026-28808","EEF-CVE-2026-28808","GHSA-3vhp-h532-mc3f","OESA-2026-2572","OESA-2026-2573","UBUNTU-CVE-2026-28808"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass","data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"Erlang OTP inets","requires_auth":"none","summary":"Attackers can bypass directory authentication to access protected CGI scripts in Erlang OTP inets when ScriptAlias is used.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"EEF","cpe":[{"product":"erlang\\/inets","vendor":"erlang"},{"product":"erlang\\/otp","vendor":"erlang"}],"cvss":{"score":8.3,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:L/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-551","name":"Incorrect Behavior Order: Authorization Before Parsing and Canonicalization"},{"id":"CWE-863","name":"Incorrect Authorization"}],"description":"Incorrect Authorization vulnerability in Erlang OTP (inets modules) allows unauthenticated access to CGI scripts protected by directory rules when served via script_alias.\n\nWhen script_alias maps a URL prefix to a directory outside DocumentRoot, mod_auth evaluates directory-based access controls against the DocumentRoot-relative path while mod_cgi executes the script at the ScriptAlias-resolved path.
