CVE-2026-45307: CWE-601: URL Redirection to Untrusted Site ('Open Redirect') in murtaza-nasir speakr
Speakr is a personal, self-hosted web application designed for transcribing audio recordings. Prior to 0.8.20-alpha, the is_safe_url() helper used to validate post-login redirect targets applied urljoin(request.host_url, target) before parsing, while the controller passed the raw target to redirect(). A scheme-relative input such as ////evil.com resolved to a same-host URL during validation but was emitted verbatim in the Location header, where the browser interpreted it as a network-path-relative redirect to an attacker-controlled host. This vulnerability is fixed in 0.8.20-alpha.
AI Analysis
Technical Summary
Speakr versions before 0.8.20-alpha contain an open redirect vulnerability (CWE-601) due to improper validation of post-login redirect targets. The is_safe_url() helper function validates URLs by applying urljoin(request.host_url, target), which resolves scheme-relative URLs like ////evil.com to a same-host URL during validation. However, the controller passes the raw target to redirect(), causing the browser to interpret the Location header as a network-path-relative redirect to an attacker-controlled host. This discrepancy enables attackers to redirect users to untrusted sites. The vulnerability is addressed in speakr 0.8.20-alpha.
Potential Impact
Successful exploitation allows an attacker to redirect users to arbitrary external websites after login, potentially facilitating phishing or other social engineering attacks. The vulnerability impacts confidentiality and integrity to a limited extent (CVSS impact metrics: C:L, I:L, A:N). There are no known exploits in the wild at this time.
Mitigation Recommendations
This vulnerability is fixed in speakr version 0.8.20-alpha. Users should upgrade to this version or later to remediate the issue. No official patch or temporary workaround is indicated beyond upgrading. Patch status is not explicitly confirmed beyond the fix in 0.8.20-alpha; users should verify with the vendor for the latest remediation guidance.
