CVE-2026-72835

filebrowser versions before v2.63.21 fail to canonicalize paths before evaluating access rules, allowing authenticated users to bypass administrator-defined deny rules using case-variant or backslash-separated paths. Attackers can request files with alternate path representations that match no ru...

CVE-2026-72836 FileBrowser before 2.63.19 Case Sensitivity Authentication Bypass

FileBrowser before 2.63.19 does not account for case-insensitive filesystems when checking home directory ownership during self-registration. When Signup and CreateUserDir are enabled and FileBrowser's root is on a case-insensitive filesystem confirmed on Windows/NTFS, two self-registered usernam...

CVE-2026-70429

A flaw was found in Jenkins. Due to inconsistent handling of case sensitivity in user and group names, an attacker with the ability to create new users or groups could exploit this vulnerability. By crafting user or group names that case-insensitively match existing ones, the attacker could...

GO-2026-5287 Traefik: HTTP/3 mTLS bypass via exact SNI TLSOptions lookup for wildcard and mixed-case hosts in github.com/traefik/traefik

Traefik's HTTP/3 TLS configuration selection is vulnerable to a bypass when using wildcard or mixed-case hosts in the SNI. The HTTP/3 QUIC path performed a direct, case-sensitive lookup on the SNI value to select the applicable TLS configuration. This lookup failed to match wildcard host patterns...

CVE-2026-71315

Nuxt is an open-source web development framework for Vue.js. From 3.21.7 until 3.21.10 and 4.5.1, mixed-case routeRules keys can fail to match case-folded lookups when router.options.sensitive is false and drop appMiddleware authorization gates. This is caused by an incomplete fix for...

CVE-2026-71315 Nuxt route rules silently dropped for mixed-case paths, bypassing appMiddleware auth gates (incomplete fix for CVE-2026-53721)

Nuxt is an open-source web development framework for Vue.js. From 3.21.7 until 3.21.10 and 4.5.1, mixed-case routeRules keys can fail to match case-folded lookups when router.options.sensitive is false and drop appMiddleware authorization gates. This is caused by an incomplete fix for...

CVE-2026-70429

Jenkins 2.575 and earlier, LTS 2.568.1 and earlier handles case-insensitivity in user names and group names inconsistently, allowing attackers able to create new users or groups with names that case-insensitively match other characters to impersonate other users or be granted their permissions in...

Jenkins LTS < 2.568.2 / Jenkins weekly < 2.576 Multiple Vulnerabilities

According to its its self-reported version number, the version of Jenkins running on the remote web server is Jenkins LTS prior to 2.568.2 or Jenkins weekly prior to 2.576. It is, therefore, affected by multiple vulnerabilities: - Jenkins 2.575 and earlier, LTS 2.568.1 and earlier handles...

Improper handling of case sensitivity allows privilege escalation

Jenkins 2.575 and earlier, LTS 2.568.1 and earlier handles case-insensitivity in user names and group names inconsistently. While the canonical ID for a case-insensitive user or group name is created by lowercasing the name, comparisons of user names and group names are done using...

CVE-2026-66883

OIDCC_Plugin: The vulnerability CVE-2026-66883 affects oidcc_plug (Oidcc.Plug.Authorize) where get_req_header(conn, "User-Agent") is matched case-sensitively, causing the user-agent binding to be inert and bypassable across requests. As a result, the binding check can pass unconditionally, even w...

SUSE CVE-2026-55170

OpenFGA is an authorization/permission engine built for developers. Prior to 1.18.0, when MySQL is being used as the datastore and authorization decisions rely on case-sensitive user strings, the tuple, changelog, and authorizationmodel identifier columns can compare case-distinct values such as...

gnutls: GnuTLS: Policy bypass due to case-sensitive nameConstraints comparison

A flaw was found in gnutls. This vulnerability occurs because gnutls performs case-sensitive comparisons of nameConstraints labels, specifically for dNSName DNS or rfc822Name email constraints within excludedSubtrees or permittedSubtrees. A remote attacker can exploit this by crafting a leaf...
