v2.0.10

Security fixes

This release includes a fix for the following security issue:

Unauthenticated memory-leak DoS via aborted WebSocket handshake

Affects: upgradeWebSocket. A WebSocket upgrade request with a missing or malformed Sec-WebSocket-Key header leaked the request's IncomingMessage and left a promise pending, even though no connection was established. Since the route is reachable pre-handshake without authentication, an attacker could flood it to gradually exhaust memory. GHSA-9mqv-5hh9-4cgg

---

Users of upgradeWebSocket are encouraged to upgrade to this version.

v2.0.9

Release notes

Sourced from @​xmldom/xmldom's releases.

0.8.15

Commits

Fixed

• Security: parsing a deeply or repeatedly namespaced document no longer consumes quadratic memory; the in-scope namespace map is inherited through the prototype chain instead of being copied for every prefix-declaring element (O(N) instead of O(N²)), preventing a denial-of-service reachable from DOMParser.parseFromString with default options. Serialized output is byte-identical. GHSA-965w-775f-mr7g
• Security: attribute de-duplication during parsing is now O(M) instead of O(M²); the NamedNodeMap parse-time dedup path uses a null-prototype membership index, so a well-formed document with a hostile number of duplicate attributes can no longer wedge the parse. Attribute order and duplicate resolution (last value wins, first position kept) are byte-identical, preserving the XML no-duplicate-attributes well-formedness constraint. GHSA-8344-3jmq-59r6
• Security: trimming trailing whitespace from an XML end tag (ETag) is now anchored so it runs in linear time instead of backtracking quadratically on a long whitespace run, preventing a ReDoS reachable from DOMParser.parseFromString. Trimmed output is byte-identical. GHSA-x4fp-j954-r2f4
• Security: malformed-input recovery is now linear instead of quadratic — the malformed tag-name scan terminates at an embedded <, and Node.prototype.normalize() merges adjacent text nodes in O(K) instead of O(K²) (also reachable programmatically), per normalize() in the WHATWG DOM spec. DOM output is unchanged; only the reported error text differs. GHSA-93r5-fhx6-vmg9
• Security: XMLSerializer.serializeToString() under { requireWellFormed: true } now rejects a DocType name that is not a valid XML Name, throwing InvalidStateError — matching the sibling publicId/systemId/internalSubset checks and preventing XML injection via DocumentType.name. GHSA-27p8-2357-5qqv
• Security: XMLSerializer.serializeToString() under { requireWellFormed: true } now validates a processing-instruction target as an XML NCName and rejects a case-insensitive xml, throwing InvalidStateError — a check 0.8.x did not previously perform, preventing PI-target injection via >, ?, or whitespace. GHSA-c7q8-3ch8-vqpv
• Security: Document.createEntityReference() now rejects an invalid XML Name at creation, and XMLSerializer.serializeToString() under { requireWellFormed: true } validates an EntityReference nodeName as an XML Name, throwing InvalidStateError — preventing XML injection via an entity-reference name. GHSA-6gmq-8vp8-gcm6
• Security: the parser now reports a not-well-formed end tag whose valid name is followed by trailing content as a recoverable error instead of accepting it silently, per the XML ETag production; parsing recovers to the byte-identical DOM. Consumers that want strict rejection can escalate the reported error to fatal via the parser's errorHandler. GHSA-6h8r-xr42-gp59

Commits

Fixed

• Security: XMLSerializer.serializeToString() now also rejects invalid element and attribute names when { requireWellFormed: true } is passed, throwing InvalidStateError for a name that is not a valid XML QName (this covers the namespace prefix, which surfaces in the element qualified name or in a synthesized xmlns: declaration). This prevents XML injection via createElement() / setAttribute(), extending the existing requireWellFormed checks to the serialized name set. GHSA-w2rr-34g9-rvrj GHSA-4w3w-2rp5-g8jm

Updates hono from 4.12.33 to 4.13.7

Release notes

Sourced from hono's releases.

v4.13.7

Security fixes

This release includes a fix for the following security issue:

hono/jsx renders plain strings unescaped in boundary components, leading to XSS

Affects: Suspense, ErrorBoundary, and Context.Provider in hono/jsx, and renderToString() / renderToReadableStream() in hono/jsx/dom/server. Fixes missing HTML escaping for a plain string placed directly as a child or fallback of these components, or as the root value of the server rendering functions, so untrusted strings could be emitted as markup. GHSA-hxh3-vqpv-xpqv

---

Users who render untrusted strings inside Suspense, ErrorBoundary, or Context.Provider, or pass them directly to hono/jsx/dom/server, are strongly encouraged to upgrade to this version.

v4.13.6

What's Changed

• fix(client): keep a param value of "index" in $url() and $path() in honojs/hono#5297
• fix(client): normalize root WebSocket URLs in honojs/hono#5291
• fix(types): allow symbol keys in Context get and set fallbacks in honojs/hono#5300
• chore: bump editorconfig-checker in honojs/hono#5336
• refactor(on-handler): use forEach for consistent handler iteration in honojs/hono#5326

Full Changelog: honojs/hono@v4.13.5...v4.13.6

v4.13.5

Security fixes

This release includes fixes for the following security issues:

Query parser reads parameters after the URL fragment, causing cache-key and proxy interpretation differentials

Affects: Cache Middleware and applications behind a proxy, WAF, or logging layer that inspects query strings. Fixes query parsing that did not stop at the URL fragment, so a ? after a # was treated as the start of a query string and the application could read parameters that the other component never saw. GHSA-crvj-82cr-hjcx

Incomplete fix for CVE-2026-39408: toSSG() still writes files outside the output directory

Affects: toSSG() for Static Site Generation. Fixes a path normalization gap where consecutive parent-directory segments in ssgParams values were not fully collapsed, bypassing the containment check added in 4.12.12. GHSA-gqvv-2mrq-wpjv

Unbounded dot-notation nesting in parseBody() can cause memory exhaustion

Affects: parseBody() when dot-notation parsing is enabled. Fixes unbounded expansion of dot-separated field names, where a small request body could allocate a disproportionately large object graph and concurrent requests could exhaust the heap. GHSA-g6gw-c38x-mqfc

---

Users who use Cache Middleware, deploy behind a proxy or WAF that inspects query strings, use Static Site Generation, or use parseBody({ dot: true }) are strongly encouraged to upgrade to this version.

v4.13.4

What's Changed

• fix(request): handle params on unmatched requests in honojs/hono#5268
• fix(jsx/dom): execute previous ref cleanup when ref prop changes on re-render in honojs/hono#5264
• fix(reg-exp-router): associate wildcard middleware with matching routes in honojs/hono#5266
• perf(router): share null object creation in honojs/hono#5267

Release notes

Sourced from @​xmldom/xmldom's releases.

0.8.15

Commits

Fixed

• Security: parsing a deeply or repeatedly namespaced document no longer consumes quadratic memory; the in-scope namespace map is inherited through the prototype chain instead of being copied for every prefix-declaring element (O(N) instead of O(N²)), preventing a denial-of-service reachable from DOMParser.parseFromString with default options. Serialized output is byte-identical. GHSA-965w-775f-mr7g
• Security: attribute de-duplication during parsing is now O(M) instead of O(M²); the NamedNodeMap parse-time dedup path uses a null-prototype membership index, so a well-formed document with a hostile number of duplicate attributes can no longer wedge the parse. Attribute order and duplicate resolution (last value wins, first position kept) are byte-identical, preserving the XML no-duplicate-attributes well-formedness constraint. GHSA-8344-3jmq-59r6
• Security: trimming trailing whitespace from an XML end tag (ETag) is now anchored so it runs in linear time instead of backtracking quadratically on a long whitespace run, preventing a ReDoS reachable from DOMParser.parseFromString. Trimmed output is byte-identical. GHSA-x4fp-j954-r2f4
• Security: malformed-input recovery is now linear instead of quadratic — the malformed tag-name scan terminates at an embedded <, and Node.prototype.normalize() merges adjacent text nodes in O(K) instead of O(K²) (also reachable programmatically), per normalize() in the WHATWG DOM spec. DOM output is unchanged; only the reported error text differs. GHSA-93r5-fhx6-vmg9
• Security: XMLSerializer.serializeToString() under { requireWellFormed: true } now rejects a DocType name that is not a valid XML Name, throwing InvalidStateError — matching the sibling publicId/systemId/internalSubset checks and preventing XML injection via DocumentType.name. GHSA-27p8-2357-5qqv
• Security: XMLSerializer.serializeToString() under { requireWellFormed: true } now validates a processing-instruction target as an XML NCName and rejects a case-insensitive xml, throwing InvalidStateError — a check 0.8.x did not previously perform, preventing PI-target injection via >, ?, or whitespace. GHSA-c7q8-3ch8-vqpv
• Security: Document.createEntityReference() now rejects an invalid XML Name at creation, and XMLSerializer.serializeToString() under { requireWellFormed: true } validates an EntityReference nodeName as an XML Name, throwing InvalidStateError — preventing XML injection via an entity-reference name. GHSA-6gmq-8vp8-gcm6
• Security: the parser now reports a not-well-formed end tag whose valid name is followed by trailing content as a recoverable error instead of accepting it silently, per the XML ETag production; parsing recovers to the byte-identical DOM. Consumers that want strict rejection can escalate the reported error to fatal via the parser's errorHandler. GHSA-6h8r-xr42-gp59

Commits

Fixed

• Security: XMLSerializer.serializeToString() now also rejects invalid element and attribute names when { requireWellFormed: true } is passed, throwing InvalidStateError for a name that is not a valid XML QName (this covers the namespace prefix, which surfaces in the element qualified name or in a synthesized xmlns: declaration). This prevents XML injection via createElement() / setAttribute(), extending the existing requireWellFormed checks to the serialized name set. GHSA-w2rr-34g9-rvrj GHSA-4w3w-2rp5-g8jm
