CVE-2026-54286

CVE-2026-54286 concerns Hono’s path traversal in the Windows environment via encoded backslash (%5C) in the request path. A prior issue (pre-4.12.25) causes %5C to decode to a backslash, which Windows path resolution treats as a separator, allowing a crafted URL segment (e.g., admin\secret.txt) t...

GHSA-M999-J542-5W3R Open Redirect Bypass in miniflux-v2

Summary The URL restrictions in miniflux-v2 can be bypassed by attackers, leading to an open redirect vulnerability. Details Normally, the redirect URL needs to be validated using IsRelativePath. There are some security measures in place, such as requiring relative paths, prohibiting host and...

Open Redirect

Overview Affected versions of this package are vulnerable to Open Redirect in the getLoginRedirect function. An attacker can redirect users to an attacker-controlled hostname by exploiting a backslash bypass in the redirect target. Remediation Upgrade cakephp/authentication to version 3.3.6, 4.1....

CakePHP Authentication: Open redirect weakness via backslash bypass

Impact The getLoginRedirect method contains a weakness to backslash bypasses allowing redirect targets with attacker controlled hostnames. Patches 2.11.1, 3.3.6 and 4.1.1 contain a fix for this issue. Workarounds If you are unable to upgrade, you should consider adding application validation to t...

GHSA-J5R2-4C8J-XC3M Gitea: Open Redirect via redirect_to

Details Despite the validation within urlIsRelative in modules/httplib/url.go, an open redirect is still possible due to usage of directory traversal sequences plus a back-slash in the "redirectto" parameter. PoC When a user uses this URL to login:...

Open Redirect

Overview Affected versions of this package are vulnerable to Open Redirect via the redirectto parameter when directory traversal sequences and a backslash are used. An attacker can redirect users to arbitrary external sites by crafting a malicious URL, potentially leading to phishing, token theft...
