CVE-2026-126351

Addressable: Denial of service in URI path normalization

Addressable is an alternative implementation to the URI implementation that is part of Ruby's standard library. Prior to 2.9.1, Addressable::URI.normalize_path repeatedly scans and rewrites paths while removing only one nested dot segment per pass, producing quadratic work. URI#normalize, URI#normalized_path, URI#join, URI#==, and URI#=== inherit the behavior, so processing a sufficiently long attacker-controlled URI can consume a worker thread and cause denial of service on every Ruby implementation. URI.parse alone and code that never normalizes, compares, or joins untrusted URIs are unaffected. This issue is fixed in version 2.9.1.

CVE-2026-126353

Addressable: Regular Expression Denial of Service in Addressable templates with several exploded variables

Addressable is an alternative implementation to the URI implementation that is part of Ruby's standard library. From 2.3.0 until 2.9.1, URI template expressions containing several exploded variables generate ambiguous regular expressions that can divide a run of members among the variables in polynomially many ways. Template#match or Template#extract processing of an attacker-controlled URI can therefore consume a thread and cause denial of service. The flaw affects MRI Ruby before 3.2 and JRuby, TruffleRuby 40.0, and plus or number-sign expressions on MRI Ruby 3.2. MRI Ruby 3.3 and later, URI parsing, and Template#expand are unaffected. This issue is fixed in version 2.9.1.

CVE-2026-126354

Addressable URI normalization resolves some dotted path segments to the wrong path

Addressable is an alternative implementation to the URI implementation that is part of Ruby's standard library. From 2.2.5 until 2.9.1, Addressable::URI.normalize_path can resolve a path containing leading parent segments and later parent segments to a different path than an RFC 3986 resolver. URI#normalize, URI#join, URI#==, and URI#=== inherit the result. An application that authorizes the Addressable-normalized path but sends the original URI to another resolver can allow access outside the intended path allowlist. Applications that use the same normalized value for authorization and the request, or reject parent segments, are unaffected. This issue is fixed in version 2.9.1.

CVE-2026-126355

Hono: `csrf()` does not check requests sent by hyperlink auditing (`text/ping`)

Hono is a Web application framework that provides support for any JavaScript runtime. Prior to 4.13.16, csrf() limits origin validation to the content types normally sent by HTML forms and therefore does not validate text/ping requests generated by Chromium hyperlink auditing. Chrome and Edge can send a cross-origin credentialed POST without a CORS preflight through an &lt;a ping&gt; action, and the middleware then skips both Origin and Sec-Fetch-Site checks. The fixed request body limits exploitation to state-changing endpoints whose effect is selected by the path or query string and does not depend on submitted body data. The user's cookie must accompany the request, which generally requires a same-site origin or a cookie configured with SameSite=None, and Firefox does not send hyperlink-auditing pings by default. This issue is fixed in version 4.13.16.

Hono: `validator('form')` skips validation for `multipart/form-data` requests with extra parameters

Hono is a Web application framework that provides support for any JavaScript runtime. From 4.5.1 until 4.13.16, validator('form') uses a strict whole-header pattern that fails to recognize multipart/form-data when its Content-Type includes another legal parameter or extra whitespace after a semicolon. The validation callback receives an empty object even though c.req.parseBody() or c.req.formData() can still parse and expose all submitted fields to the handler. An unauthenticated client can therefore bypass allow-list or required-field checks when the application relies on the form validator and its callback accepts an empty object. application/x-www-form-urlencoded requests are not affected. This issue is fixed in version 4.13.16.

Hono: `mount()` and `app.mount()` can forward a path that bypasses middleware scoped inside the mount prefix

Hono is a Web application framework that provides support for any JavaScript runtime. Prior to 4.13.16, mount() and app.mount() can remove a dynamic mount prefix using the route-pattern length rather than the matched-prefix length, allowing a crafted path to be forwarded as a protected inner route while the outer application routes the original path. Since 4.12.21, rebuilding the forwarded URL from the decoded pathname can also convert a decoded backslash to a slash and collapse parent-directory segments, again causing the mounted application to receive a protected path. An unauthenticated client can use either applicable path transformation to reach a mounted route without authentication or authorization middleware scoped to a subpath inside the mount prefix. This issue is fixed in version 4.13.16.

Dokploy < 0.31.1 Broken Access Control via readAppMonitoring

Dokploy before 0.31.1 contains a missing ownership check vulnerability in the readAppMonitoring tRPC procedure that allows authenticated attackers to access container metrics belonging to other organizations by supplying an arbitrary appName. Attackers can query getApplicationStats with any application name, including the fixed "dokploy" control-plane service name, to read CPU, memory, network I/O, and block I/O metrics for containers they do not own on self-hosted multi-tenant instances.

Hono: RegExpRouter skips wildcard middleware for some route sets and for paths with an encoded line terminator

Hono is a Web application framework that provides support for any JavaScript runtime. From 4.1.4 until 4.13.16, RegExpRouter can omit wildcard middleware in three version-specific cases: since 4.13.0, middleware using the explicit default parameter pattern in /api/:tenant{[^/]+}/admin/* is not applied to a route written as /api/:tenant/admin/:id; since 4.1.4, middleware on /admin/* is not applied to a route registered as /admin* for paths under /admin/; and since 4.4.0, a request path containing an encoded line terminator can reach the not-found handler without wildcard middleware. The default SmartRouter selects RegExpRouter for most applications, and the router's registration-time coverage calculation treated the first two matching pattern pairs as different while its compiled wildcard did not match line terminators in the third case. An unauthenticated client can reach a route handler or the not-found handler without authentication or authorization middleware registered on the wildcard path. TrieRouter, LinearRouter, and PatternRouter apply the middleware in the three described cases. This issue is fixed in version 4.13.16.

Hono: `css` helper does not escape a closing tag split between the template and an interpolated value, allowing HTML injection

Hono is a Web application framework that provides support for any JavaScript runtime. From 3.12.0 until 4.13.16, the css helper in hono/css escapes interpolated string values separately and therefore fails to neutralize a closing style tag when &lt; ends the template text or a preceding value and / begins the next attacker-controlled value. During server-side rendering, the combined output can close the &lt;Style /&gt; element early and cause the remainder of the interpolated value to be interpreted as HTML. Applications that place an untrusted string immediately after &lt; in a css template, including adjacent untrusted interpolations, can expose viewers to attacker-controlled HTML or script and information accessible to that page. Other uses of the css helper are not affected. This issue is fixed in version 4.13.16.

OpenTelemetry Python: Denial of service through quadratic-time traceparent parsing in opentelemetry-api

OpenTelemetry Python provides the Python API and SDK for OpenTelemetry. Prior to 1.45.2, TraceContextTextMapPropagator.extract() in opentelemetry-api can perform quadratic-time regular-expression backtracking on a malformed traceparent value containing a trace-context prefix, a long whitespace sequence, and an embedded newline. Exploitation requires an attacker-controlled carrier that preserves embedded newlines and permits a sufficiently large value, because conforming HTTP header values cannot contain embedded newlines. JSON-based carriers, including applicable MCP request metadata integrations, can preserve the required newline depending on the SDK, instrumentation, and message-size limits. Parsing on an asynchronous server's event-loop thread can consume excessive CPU and delay unrelated requests, while the advisory does not establish disclosure, modification, or code execution. This issue is fixed in version 1.45.2.

Astro: XSS via attribute injection in dynamic tag names

Astro is a web framework for content-driven websites. Prior to 7.4.5, Astro rendered a string used as a dynamic element name as raw HTML after applying an incomplete character filter. A / in the string could make an HTML parser treat the remainder as attributes, allowing untrusted element-name input to inject event-handler markup. The .astro dynamic-tag renderer, JSX renderer, and MDX renderer were affected, and exploitation required an application to use request-controlled or stored untrusted data as all or part of an element name. This issue is fixed in version 7.4.5.

Astro: Reflected XSS via unescaped slot names in @astrojs/svelte

Astro is a web framework for content-driven websites. From 5.7.3 until 9.1.2, the @astrojs/svelte renderer inserted a named slot into the quoted name attribute of an astro-slot wrapper without HTML escaping. Request-controlled slot names containing a quote could terminate the attribute and inject active HTML. Exploitation required a hydrated Svelte component using a client:* directive and dynamic rendering of the attacker-chosen slot; components that did not render that slot emitted only Astro's escaped fallback content. Both server rendering and client-side hydration used the unsafe slot name. This issue is fixed in version 9.1.2.
