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-2026-126354 in the wild and no public exploit code.\nExposure: An affected version is only exploitable if your software calls Addressable::URI.normalize_path, URI#normalize or URI#join. Many projects that include it are not exposed.\n\nAffected packages and fixed versions:\n- addressable (RubyGems): affected from 2.2.5; fixed in 2.9.1\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.\n   If an affected version is present, also search the code for calls to Addressable::URI.normalize_path, URI#normalize or URI#join and report whether any exist.\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-2026-126354/ (Markdown: https://insights.sbomify.com/CVE-2026-126354/index.md)","id":"CVE-2026-126354","markdown":"https://insights.sbomify.com/CVE-2026-126354/index.md","name":"CVE-2026-126354","record":{"aliases":["GHSA-8gmh-2hhj-2hv9"],"analysis":{"component_type":"library","exploitable_when_present":false,"fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Ruby URI library","requires_auth":"none","requires_specific_call":true,"summary":"Applications using Addressable normalization for authorization but sending original URIs may allow access outside the intended path allowlist.","user_interaction":"not_required","vuln_class":"path_traversal","vulnerable_functions":["Addressable::URI.normalize_path","URI#normalize","URI#join"]},"analysis_generated_by":"sbomify/insights-2b-fp8","assigner":"GitHub_M","cpe":[],"cvss":{"score":4.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-436","name":"Interpretation Conflict"},{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"Addressable is an alternative implementation to the URI implementation that is part of Ruby's standard library. From 2.2.5 until 2.9.1, Addressable::URI.normalize_path can resolve a path containing leading parent segments and later parent segments to a different path than an RFC 3986 resolver. URI#normalize, URI#join, URI#==, and URI#=== inherit the result. An application that authorizes the Addressable-normalized path but sends the original URI to another resolver can allow access outside the intended path allowlist. Applications that use the same normalized value for authorization and the request, or reject parent segments, are unaffected.
