Vault and Vault Enterprise did not consistently evaluate ACL policies against the canonical form of resource and policy names. This may allow an authenticated user with delegated permissions to bypass an explicit deny restriction and access a protected resource or assign a denied policy, potentially leading to privilege escalation. This vulnerability (CVE-2026-89322) is fixed in Vault Community Ed…

Backstage is an open framework for building developer portals. Prior to 3.3.1, 3.4.1, 4.0.3 and 4.1.0, the @backstage/plugin-scaffolder-backend package is affected by scaffolder action input authorization bypass. An authenticated user with access to affected Scaffolder templates could bypass configured action restrictions. Depending on integration credentials, this could grant unauthorized access …

Kiteworks Email Protection Gateway rejected certain configuration settings, but its validation did not recognize every form in which they could be supplied. An authenticated administrator could potentially use an unrecognized form to have a file of their choosing written to the gateway and executed, resulting in code execution as the gateway service account.

Hugo versions from v0.162.0 before v0.166.0 contain a case-sensitive validation flaw in the security.http.urls IP-literal deny rule that allows attackers to bypass restrictions. Attackers can use mixed-case URL schemes in resources.GetRemote calls to fetch from restricted IP addresses like localhost.

Grav before 2.0.25 ships web server configuration samples whose access-control deny rules are matched case-sensitively. In webserver-configs/web.config (IIS), every deny rule (user_sensitive_folders, user_accounts, user_data, user_error_redirect, user_pages, system, vendor, ignore_folders) sets ignoreCase="false" on its URL Rewrite element, overriding the IIS default of ignoreCase="true"; …

OpenClaw (paquete npm 'openclaw') versiones anteriores a 2026.7.1 presenta una falla en la validación de mayúsculas y minúsculas que permite a actores maliciosos eludir controles de seguridad y crear trabajos cron persistentes. Un agente con capacidad de herramientas puede ser manipulado para ejecutar comandos arbitrarios con los privilegios del proceso OpenClaw, comprometiendo servidores de aplicaciones altas en entornos empresariales de LATAM.

OpenClaw's Matrix integration (npm package @openclaw/matrix) versions >= 2026.2.2 and < 2026.8.1 lowercase complete Matrix user IDs — including historical localparts and the case-sensitive server-name portion — when deriving the OpenClaw authorization identity. As a result, distinct authenticated Matrix accounts can normalize to the same authorization identity. A Matrix participant controlling a c…

Tinyauth is an authentication and authorization server. Prior to 5.1.2, Tinyauth compares forwarded hostnames case-sensitively while reverse proxies route equivalent hostnames case-insensitively, allowing an authenticated low-privilege user to bypass per-app access controls with a differently cased hostname. The lookup in internal/service/access_controls_service.go through lookupStaticACLs and Get…

Flask-Reuploaded provides file uploads for Flask. From 1.5.0 until 1.6.0, UploadSet.save(storage, name=...) in src/flask_uploads/flask_uploads.py applies lowercase_ext to the default upload path but uses the case-preserving extension helper for a caller-supplied name before extension_allowed evaluates an AllExcept denylist. An attacker who controls the name override can use a mixed-case dangerous …
