Interpretation Conflict

Overview Affected versions of this package are vulnerable to Interpretation Conflict due to case-sensitive handling of the host matching process. An attacker can bypass access control policies by sending requests with hostnames that differ only in letter casing, potentially gaining unauthorized...

Heimdall: Case-sensitive handling of URL-encoded slashes may lead to inconsistent path interpretation

Summary Heimdall handles URL-encoded slashes %2F in a case-sensitive manner, while percent-encoding is defined to be case-insensitive. As a result, the lowercase equivalent %2f is not recognized and therefore not processed as expected when allowencodedslashes is set to off the default setting. Th...

PT-2026-37187

Name of the Vulnerable Software and Affected Versions Heimdall versions prior to 0.17.14 Description Heimdall performs host matching in a case-sensitive manner, which conflicts with the case-insensitive nature of HTTP hostnames. This discrepancy allows a request host that differs only in letter...

Marko: XSS via case-insensitive script/style closing tag bypass in runtime HTML escaping

Summary When dynamic text is interpolated into a or tag the Marko runtime failed to prevent tag breakout when the closing tag used non-lowercase casing. An attacker able to place input inside a or block could break out of the tag with , , etc. and inject arbitrary HTML/JavaScript, resulting in...

JLSEC-2026-115 Deno has an incomplete fix for command-injection prevention on Windows — case-insensitive extension bypass

Summary A prior patch aimed to block spawning Windows batch/shell files by returning an error when a spawned path’s extension matched .bat or .cmd. That check performs a case-sensitive comparison against lowercase literals and therefore can be bypassed when the extension uses alternate casing for...

BIT-GOLANG-2026-33810 Case-sensitive excludedSubtrees name constraints cause Auth Bypass in crypto/x509

When verifying a certificate chain containing excluded DNS constraints, these constraints are not correctly applied to wildcard DNS SANs which use a different case than the constraint. This only affects validation of otherwise trusted certificate chains, issued by a root CA in the...

SUSE CVE-2026-31842

Tinyproxy through 1.11.3 is vulnerable to HTTP request parsing desynchronization due to a case-sensitive comparison of the Transfer-Encoding header in src/reqs.c. The ischunkedtransfer function uses strcmp to compare the header value against "chunked", even though RFC 7230 specifies that...

CVE-2026-33810

CVE-2026-33810 affects the Go crypto/x509 certificate chain validation. The issue occurs when verifying a chain with excluded DNS constraints: constraints are not consistently applied to wildcard DNS SANs if the SANs’ case differs from the constraint, which can affect validation of otherwise trus...
