Vulnerability from github – Published: 2026-05-14 13:08 – Updated: 2026-05-14 13:08

Summary

Absinthe: Quadratic fragment-name uniqueness check

Details

Summary

An unauthenticated attacker can stall an Absinthe-backed GraphQL endpoint by submitting a query that contains many fragment definitions. The fragment-name uniqueness validation phase is O(N²) in the number of fragments, so a single modestly-sized request burns seconds of CPU per worker, and sustained traffic exhausts the worker pool (denial of service).

Introduced like with https://github.com/absinthe-graphql/absinthe/commit/0b46e3bcc06c0d3797bacd64761b908a84646c1d#diff-e540120c6a98cc1013be110d08e9d029511b9aabd26ad5f7f643c36834caac14

Details

Absinthe.Phase.Document.Validation.UniqueFragmentNames (lib/absinthe/phase/document/validation/unique_fragment_names.ex:14-40) walks every fragment in input.fragments via run/2, calling process/2 on each one. process/2 then calls duplicate?/2, which evaluates Enum.count(fragments, fn f -> f.name == name end) — a full linear scan of the fragment list — for every individual fragment. The result is N · N name comparisons per document.

input.fragments is built directly from the GraphQL query text the caller sends at the head of the pipeline, so N is attacker-controlled. A minimum-size fragment definition (fragment a on T{f}) is roughly 16 bytes, so a ~1 MB document carries ~60 000 fragments and forces ~3.6 × 10⁹ comparisons inside this one phase. Phoenix's default 8 MB body limit allows substantially larger blow-ups if operators have not lowered it. Nothing in this module caps N.

The fix is to aggregate names once per call rather than re-scanning per fragment, e.g.:

dups =
  for {name, k} <- Enum.frequencies_by(input.fragments, & &1.name),
      k > 1,
      into: MapSet.new(),
      do: name

and then check MapSet.member?(dups, fragment.name) inside process/2. That collapses the phase to O(N).

PoC

A standalone script that builds a GraphQL document with a large number of minimal fragment definitions, feeds it through Absinthe's pipeline, and times the UniqueFragmentNames phase is attached at the end of this report. Running it shows the validation time growing quadratically with the fragment count.

Impact

Algorithmic complexity / denial-of-service. Any service that exposes an Absinthe GraphQL endpoint to untrusted callers is affected: a single unauthenticated POST containing many fragment definitions pins a worker process for seconds, and modest sustained traffic exhausts the request-handling pool. No authentication, schema knowledge, or special configuration is required — only the ability to send a GraphQL query large enough to contain many fragments, which is permitted by Phoenix's default body-size limit.

GHSA-C2PC-G5QF-RFRF

Vulnerability from github – Published: 2024-12-09 20:42 – Updated: 2024-12-09 20:42

Summary

league/commonmark's quadratic complexity bugs may lead to a denial of service

Details

Impact

Several polynomial time complexity issues in league/commonmark may lead to unbounded resource exhaustion and subsequent denial of service.

Malicious users could trigger that inefficient code with carefully crafted Markdown inputs that are specifically designed to ensure the worst-case performance is reached. Sending multiple such requests in parallel could tie up all available CPU resources and/or PHP-FPM processes, leading to denial of service for legitimate users.

Patches

These vulnerabilities have been patched in version 2.6.0. All users on older versions are highly encouraged to upgrade as soon as possible.

Workarounds

If you cannot upgrade, you may be able to mitigate the issues by:

Setting very low memory_limit and max_execution_time PHP configurations to prevent runaway resource usage
Implementing rate-limiting, bot protection, or other approaches to reduce the risk of simultaneous bad requests hitting your site
Limiting the size of inputs fed into this library (specifically the max length of each line)
Limiting the use of this library to trusted users

References

Most of these issues were discovered in other Markdown parsers. You can read more about them here:

GHSA-CGXM-VR2F-6FJ8

Vulnerability from github – Published: 2026-06-19 14:50 – Updated: 2026-06-19 14:50

Summary

parse-server: Denial of service via exponential-time processing of deeply nested query operators

Details

Impact

Parse Server is vulnerable to denial of service. A remote attacker can send a single, small query (~1 KB) containing deeply nested query condition operators. Parse Server processes the nested structure with exponential time complexity, which blocks the Node.js event loop and makes the server unresponsive to all clients for the duration of processing. A single request can occupy the event loop for many seconds, and the request is repeatable. The issue affects the REST API and LiveQuery query handling and is reachable in the default configuration. Exploitation requires only the public application identifier; no user authentication is needed.

Patches

The internal query-traversal helper that previously re-walked nested arrays — causing exponential-time processing of nested $or/$and/$nor operators — was corrected to traverse queries in linear time. Additionally, the optional requestComplexity.queryDepth limit was generalized so that nested logical operators are counted even when wrapped inside field-level operators (e.g. $elemMatch, $not) or plain field names, closing a bypass of the limit on both the REST API and LiveQuery.

Workarounds

There is no complete configuration-only workaround on affected versions. Setting requestComplexity.queryDepth to a small positive integer reduces exposure but does not fully prevent the issue, because the limit can be bypassed by nesting the operators inside a field-level operator. Upgrading is strongly recommended.

Severity

8.7 (High)

Vulnerability from github – Published: 2025-02-10 18:30 – Updated: 2026-05-12 12:32

Details

A flaw was found in GnuTLS, which relies on libtasn1 for ASN.1 data processing. Due to an inefficient algorithm in libtasn1, decoding certain DER-encoded certificate data can take excessive time, leading to increased resource consumption. This flaw allows a remote attacker to send a specially crafted certificate, causing GnuTLS to become unresponsive or slow, resulting in a denial-of-service condition.
