| CVE-2026-33691 | 2 Coreruleset, Owasp | 2 Coreruleset, Owasp Modsecurity Core Rule Set | 2026-04-18 | 6.8 Medium |
| The OWASP core rule set (CRS) is a set of generic attack detection rules for use with compatible web application firewalls. Prior to versions 3.3.9 and 4.25.0, a bypass was identified in OWASP CRS that allows uploading files with dangerous extensions (.php, .phar, .jsp, .jspx) by inserting whitespace padding in the filename (e.g. photo. php or shell.jsp ). The affected rules do not normalize whitespace before evaluating the file extension regex, so the dot-extension check fails to match. This issue has been patched in versions 3.3.9 and 4.25.0. | ||||
| CVE-2026-27588 | 1 Caddyserver | 1 Caddy | 2026-04-18 | 9.1 Critical |
| Caddy is an extensible server platform that uses TLS by default. Prior to version 2.11.1, Caddy's HTTP `host` request matcher is documented as case-insensitive, but when configured with a large host list (>100 entries) it becomes case-sensitive due to an optimized matching path. An attacker can bypass host-based routing and any access controls attached to that route by changing the casing of the `Host` header. Version 2.11.1 contains a fix for the issue. | ||||
| CVE-2026-25889 | 1 Filebrowser | 1 Filebrowser | 2026-04-17 | 5.4 Medium |
| File Browser provides a file managing interface within a specified directory and it can be used to upload, delete, preview, rename and edit files. Prior to 2.57.1, a case-sensitivity flaw in the password validation logic allows any authenticated user to change their password (or an admin to change any user's password) without providing the current password. By using Title Case field name "Password" instead of lowercase "password" in the API request, the current_password verification is completely bypassed. This enables account takeover if an attacker obtains a valid JWT token through XSS, session hijacking, or other means. This vulnerability is fixed in 2.57.1. | ||||
| CVE-2026-27896 | 2 Lfprojects, Modelcontextprotocol | 2 Mcp Go Sdk, Go-sdk | 2026-04-17 | 7.5 High |
| The Go MCP SDK used Go's standard encoding/json.Unmarshal for JSON-RPC and MCP protocol message parsing in versions prior to 1.3.1. Go's standard library performs case-insensitive matching of JSON keys to struct field tags — a field tagged json:"method" would also match "Method", "METHOD", etc. This violated the JSON-RPC 2.0 specification, which defines exact field names. A malicious MCP peer may have been able to send protocol messages with non-standard field casing that the SDK would silently accept. This had the potential for bypassing intermediary inspection and coss-implementation inconsistency. Go's standard JSON unmarshaling was replaced with a case-sensitive decoder in commit 7b8d81c. Users are advised to update to v1.3.1 to resolve this issue. | ||||
| CVE-2026-27587 | 1 Caddyserver | 1 Caddy | 2026-04-16 | 9.1 Critical |
| Caddy is an extensible server platform that uses TLS by default. Prior to version 2.11.1, Caddy's HTTP `path` request matcher is intended to be case-insensitive, but when the match pattern contains percent-escape sequences (`%xx`) it compares against the request's escaped path without lowercasing. An attacker can bypass path-based routing and any access controls attached to that route by changing the casing of the request path. Version 2.11.1 contains a fix for the issue. | ||||
| CVE-2026-29054 | 1 Traefik | 1 Traefik | 2026-04-16 | 7.5 High |
| Traefik is an HTTP reverse proxy and load balancer. From version 2.11.9 to 2.11.37 and from version 3.1.3 to 3.6.8, there is a potential vulnerability in Traefik managing the Connection header with X-Forwarded headers. When Traefik processes HTTP/1.1 requests, the protection put in place to prevent the removal of Traefik-managed X-Forwarded headers (such as X-Real-Ip, X-Forwarded-Host, X-Forwarded-Port, etc.) via the Connection header does not handle case sensitivity correctly. The Connection tokens are compared case-sensitively against the protected header names, but the actual header deletion operates case-insensitively. As a result, a remote unauthenticated client can use lowercase Connection tokens (e.g. Connection: x-real-ip) to bypass the protection and trigger the removal of Traefik-managed forwarded identity headers. This issue has been patched in versions 2.11.38 and 3.6.9. | ||||
| CVE-2004-1083 | 1 Apple | 4 Darwin Streaming Server, Mac Os X, Mac Os X Server and 1 more | 2026-04-16 | 7.5 High |
| Apache for Apple Mac OS X 10.2.8 and 10.3.6 restricts access to files in a case sensitive manner, but the Apple HFS+ filesystem accesses files in a case insensitive manner, which allows remote attackers to read .DS_Store files and files beginning with ".ht" using alternate capitalization. | ||||
