When the optional allow_redirects.referer setting is enabled, the middleware copies the URI fragment (the portion after &#8216;#&#8217;) 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.<\/p>\n<p>  Severity: 8.2 | HIGH<\/p>\n<p>  Visit the link for more details, such as CVSS details, affected products, timeline, and more&#8230;\u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"<p>CVE ID :CVE-2026-67354 Published : Aug. 1, 2026, 1:17 p.m. | 32\u00a0minutes ago Description :guzzlehttp\/guzzle versions before 7.15.1 contain an information disclosure vulnerability in RedirectMiddleware.
