Vulnerability from github – Published: 2026-09-30 03:31 – Updated: 2026-09-30 03:31Uncontrolled recursion in the Gosub browser engine (gosub-engine) through 0.1.0 and main before commit 46868b3 allows a remote attacker to cause a Denial of Service (stack exhaustion and application crash) via an SVG document containing an excessive number of deeply nested elements. Because the engine does not limit the nesting depth of processed SVG nodes, rendering such a document overflows the thread stack and terminates the application. The malicious SVG can be embedded through the SRC attribute of an IMG element, and thus exploitation only requires the victim to visit an attacker-controlled web page.

GHSA-PMCG-F5M4-2GWP
Vulnerability from github – Published: 2026-05-06 12:30 – Updated: 2026-06-01 18:31In the Linux kernel, the following vulnerability has been resolved:
l2tp: Drop large packets with UDP encap
syzbot reported a WARN on my patch series 1. The actual issue is an overflow of 16-bit UDP length field, and it exists in the upstream code. My series added a debug WARN with an overflow check that exposed the issue, that's why syzbot tripped on my patches, rather than on upstream code.
syzbot's repro:
r0 = socket$pppl2tp(0x18, 0x1, 0x1) r1 = socket$inet6_udp(0xa, 0x2, 0x0) connect$inet6(r1, &(0x7f00000000c0)={0xa, 0x0, 0x0, @loopback, 0xfffffffc}, 0x1c) connect$pppl2tp(r0, &(0x7f0000000240)=@pppol2tpin6={0x18, 0x1, {0x0, r1, 0x4, 0x0, 0x0, 0x0, {0xa, 0x4e22, 0xffff, @ipv4={'\x00', '\xff\xff', @empty}}}}, 0x32) writev(r0, &(0x7f0000000080)=[{&(0x7f0000000000)="ee", 0x34000}], 0x1)
It basically sends an oversized (0x34000 bytes) PPPoL2TP packet with UDP encapsulation, and l2tp_xmit_core doesn't check for overflows when it assigns the UDP length field. The value gets trimmed to 16 bites.
Add an overflow check that drops oversized packets and avoids sending packets with trimmed UDP length to the wire.
syzbot's stack trace (with my patch applied):

When loading a specially crafted JSON input, containing a large number of ’{’, a stack exhaustion can be trigger, which could allow an attacker to cause a Denial of Service (DoS). This issue exists because of an incomplete fix for CVE-2023-1370.
The fixed version only addresses the default modes provided by JSONParser, such as MODE_RFC4627. If you create the JSONParser manually or with custom options, make sure to set the LIMIT_JSON_DEPTH option.

GHSA-PQHP-25J4-6HQ9
Vulnerability from github – Published: 2024-11-22 20:40 – Updated: 2024-11-22 20:40Summary
An attacker can send a maliciously crafted TOML to cause the parser to crash because of a stack overflow caused by a deeply nested inline structure. A similar problem occurs when attempting to stringify deeply nested objects.
The library does not limit the maximum exploration depth while parsing or producing TOML documents, nor does it offer a way to do so.
Proof of concept
require("smol-toml").parse("e=" + "{e=".repeat(9999) + "{}" + "}".repeat(9999))
Impact
Applications which parse arbitrary TOML documents may suffer availability issues if they receive malicious input. If uncaught, the crash may cause the application itself to crash. The impact is deemed minor, as the function is already likely to throw errors on invalid input and therefore to properly handle errors.
Due to the design of most JavaScript runtimes, the uncontrolled recursion does not lead to excessive memory usage and the execution is quickly aborted.
As a reminder, it is strongly advised when working with untrusted user input to expect errors to occur and to appropriately catch them.
Patches
Version 1.3.1 offers a mechanism to limit the exploration depth before halting with a TomlError when parsing, with a default cap of 1000. A same mechanism has been implemented for stringifying objects.
Please note that the parser will still throw an error upon such cases. It is, however, a now-controlled and documented behavior of the library.
Workarounds
Wrap all invocations of parse and stringify in a try/catch block.

}
Mitigation
Ensure that an end condition will be reached under all logic conditions. The end condition may include checking against the depth of recursion and exiting with an error if the recursion goes too deep. The complexity of the end condition contributes to the effectiveness of this action.
Mitigation
Increase the stack size.
CAPEC-230: Serialized Data with Nested Payloads
Applications often need to transform data in and out of a data format (e.g., XML and YAML) by using a parser. It may be possible for an adversary to inject data that may have an adverse effect on the parser when it is being processed. Many data format languages allow the definition of macro-like structures that can be used to simplify the creation of complex structures. By nesting these structures, causing the data to be repeatedly substituted, an adversary can cause the parser to consume more resources while processing, causing excessive memory consumption and CPU utilization.
CAPEC-231: Oversized Serialized Data Payloads
An adversary injects oversized serialized data payloads into a parser during data processing to produce adverse effects upon the parser such as exhausting system resources and arbitrary code execution.
