SiYuan kernel versions before 3.7.4 contain an improper restriction of excessive authentication attempts vulnerability in the CheckAuth() middleware. The middleware accepts the API token (Conf.Api.Token) via an Authorization header (Token/Bearer) or a ?token= query parameter, and neither path is protected by the application's CAPTCHA/lockout mechanism (NeedCaptcha/WrongAuthCount). As a result, an …

SiYuan before 3.7.4 contains an improper restriction of excessive authentication attempts vulnerability in the authFilePublishAccess endpoint that allows unauthenticated attackers to brute-force per-notebook publish passwords. Attackers can submit unbounded password guesses without rate limiting or CAPTCHA to gain access to password-protected published notebooks.

SiYuan before v3.7.4 improperly restricts excessive authentication attempts in the CheckAuth() middleware. The HTTP Basic Authentication branch, which guards nearly the entire /api/* surface, accepts the workspace access code (Conf.AccessAuthCode) as the Basic Auth password but never consults the CAPTCHA/lockout gate or increments the failure counter used by the cookie/session login path. This all…

El plugin 'Invisible Anti-Spam & CAPTCHA — reCAPTCHA Alternative for All Forms' para WordPress (versiones hasta 5.1) contiene una vulnerabilidad de Cross-Site Scripting (XSS) almacenado en el parámetro 'action' por falta de sanitización. Atacantes no autenticados pueden inyectar scripts maliciosos que se ejecutan cuando usuarios acceden a páginas con formularios afectados. Este riesgo impacta directamente sitios web de empresas, tiendas en línea y portales institucionales en LATAM que usan este plugin.

A unauthenticated remote peer may lead rsyslogd to crash due to a flaw in the optional imptcp module. A crafted input sequence during oversize-frame recovery can cause an invalid internal message length and terminate rsyslogd. No confidentiality or integrity impact, privilege escalation, or code execution has been identified. imtcp and the default imptcp framing modes are not affected.

Uptime Kuma's Matomo analytics integration (server/analytics/matomo-analytics.js) injects the admin-configurable Matomo `siteId` value as a bare, unquoted JavaScript expression inside a block rendered on every public status page: `_paq.push(['setSiteId', ${escapedSiteIdHTMLAttribute}]);`. The escaping pipeline used (jsesc with isScriptContext:true, then html-escaper.escape()) does not esc…

Typemill's login endpoint (POST /tm/login, ControllerWebAuth::login()) performs no rate-limiting, failed-attempt counting, or account lockout when captcha is disabled, which is the default configuration. An unauthenticated attacker can send unlimited password-guessing requests against any account, including administrators, with no throttling. The only attempt-counting/lockout logic present in the …

The Passster WordPress plugin before 4.3.6 does not perform a post-status check before returning post content from an unauthenticated REST endpoint, allowing unauthenticated users to disclose the content of non-public (draft, private, and pending) posts on sites that have a captcha provider configured.
