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-2026-67354 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- guzzlehttp/guzzle (Packagist): affected all versions; fixed in 7.15.1\n- guzzlehttp/guzzle (Packagist): affected all versions; fixed in 7.15.1\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.\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-2026-67354/ (Markdown: https://insights.sbomify.com/CVE-2026-67354/index.md)","id":"CVE-2026-67354","markdown":"https://insights.sbomify.com/CVE-2026-67354/index.md","name":"CVE-2026-67354","record":{"aliases":["DEBIAN-CVE-2026-67354","GHSA-h95v-h523-3mw8","MINI-32hp-qmpm-vfjj","MINI-53p4-q2mr-557q","MINI-5rwf-pjqh-788c","MINI-7pw7-cxgp-w69w","MINI-gj47-7rcx-f373","MINI-v63c-99m7-hw3p","MINI-w3c3-626x-x45h","MINI-xjrc-8r6q-7f25","UBUNTU-CVE-2026-67354"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"PHP HTTP client library","requires_auth":"none","summary":"Attackers can read sensitive URI fragments from Referer headers if redirect referer logging is enabled, exposing tokens or secrets.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":8.2,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-201","name":"Insertion of Sensitive Information Into Sent Data"}],"description":"guzzlehttp/guzzle versions before 7.15.1 contain an information disclosure vulnerability in RedirectMiddleware. When the optional allow_redirects.referer setting is enabled, the middleware copies the URI fragment (the portion after '#') from the referring request into the generated Referer header when following a same-scheme redirect (e.g., HTTPS to HTTPS). An attacker who controls the redirect destination can read this fragment from the incoming Referer header, potentially disclosing one-time login secrets, access tokens, state values, or other sensitive client data to a server never meant to receive it. The referer setting is disabled by default. Fixed in 7.15.1, which strips the fragment before generating the Referer value.","ecosystems":["Packagist"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"guzzlehttp/guzzle before 7.15.1 URI Fragment Disclosure via Referer","id":"CVE-2026-67354","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":null,"products":[],"type":"information_disclosure","year":"2026"},"n_packages":2,"n_references":2,"next":{"headline":"guzzlehttp/guzzle before 7.15.1 Host-only Cookie Scope","id":"CVE-2026-67355"},"packages":[{"ecosystem":"Packagist","fixed":["7.15.1"],"introduced":["0"],"last_affected":[],"package":"guzzlehttp/guzzle","purl":null,"source":"GHSA-h95v-h523-3mw8"},{"ecosystem":"Packagist","fixed":["7.15.1"],"introduced":["0"],"last_affected":[],"package":"guzzlehttp/guzzle","purl":"pkg:composer/guzzlehttp/guzzle","source":"GHSA-h95v-h523-3mw8"}],"prev":{"headline":"guzzlehttp/guzzle before 7.15.1 Unbounded Cookie Denial of Service","id":"CVE-2026-67353"},"products":["guzzle"],"published":"2026-08-01","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-08","vendors":["guzzle"]},"summary":"Attackers can read sensitive URI fragments from Referer headers if redirect referer logging is enabled, exposing tokens or secrets.","url":"https://insights.sbomify.com/CVE-2026-67354/"}
