GHSA-9G9P-9GW9-JX7F
Vulnerability from github – Published: 2026-01-27 19:18 – Updated: 2026-01-27 19:18A DoS vulnerability exists in self-hosted Next.js applications that have remotePatterns configured for the Image Optimizer. The image optimization endpoint (/_next/image) loads external images entirely into memory without enforcing a maximum size limit, allowing an attacker to cause out-of-memory conditions by requesting optimization of arbitrarily large images. This vulnerability requires that remotePatterns is configured to allow image optimization from external domains and that the attacker can serve or control a large image on an allowed domain.
Strongly consider upgrading to 15.5.10 and 16.1.5 to reduce risk and prevent availability issues in Next applications.

Vulnerability from github – Published: 2025-08-21 20:11 – Updated: 2025-08-22 15:01Dear Maintainers, I am writing to you on behalf of the Tencent AI Sec. We have identified a potential vulnerability in one of your products and would like to report it to you for further investigation and mitigation.
Summary
The jk parameter is received in pyLoad CNL Blueprint. Due to the lack of jk parameter verification, the jk parameter input by the user is directly determined as dykpy.evaljs(), resulting in the server CPU being fully occupied and the web-ui becoming unresponsive.
Details
- Endpoint: flash/addcrypted2
- affected file: https://github.com/pyload/pyload/blob/develop/src/pyload/webui/app/blueprints/cnl_blueprint.py#L123 https://github.com/pyload/pyload/blob/develop/src/pyload/core/utils/misc.py#L42

GHSA-9H5V-PFQQ-X599
Vulnerability from github – Published: 2026-06-15 20:15 – Updated: 2026-06-15 20:15Summary
A regular expression denial-of-service (ReDoS) vulnerability has been discovered in ua-parser-js when using the Client Hints API. By sending a crafted Sec-CH-UA-Model header to an application that calls UAParser(headers).withClientHints(), an attacker can cause the parser to spend excessive CPU time due to catastrophic backtracking in the device regex:
/ ([\w ]+) miui\/v?\d/i
Unlike when using the User-Agent value, which has a hard limit of UA_MAX_LENGTH = 500, when using Client Hints, values are copied without a length limit before being passed into regex parsing.
PoC
const { UAParser } = require('ua-parser-js');
const headers = {
'sec-ch-ua-platform': '"Android"',
'sec-ch-ua-mobile': '?1',
'sec-ch-ua-model': '"' + 'A '.repeat(25000) + '"'
};
const t0 = process.hrtime.bigint();
UAParser(headers).withClientHints();
const ms = Number(process.hrtime.bigint() - t0) / 1e6;
if (ms > 100) {
console.log('Potential ReDoS');
}
Impact
This vulnerability allows an unauthenticated attacker to trigger a denial-of-service condition in any server-side application that uses UAParser(headers).withClientHints(). A single request with a ~32,000-character model value can consume over 400ms of CPU time, with parsing time growing polynomially with input length. The impact is availability only, there is no confidentiality or integrity impact.
Affected Versions
ua-parser-js versions >=2.0.1, <=2.0.9 are affected. The withClientHints() API is not present in version 0.7.x or 1.x.
Patches
A patch has been released to fix the vulnerable regular expression and limit the Client Hints input. Users should update to version 2.0.10 or later.

"details": "### Summary\n\nA regular expression denial-of-service (ReDoS) vulnerability has been discovered in `ua-parser-js` when using the Client Hints API. By sending a crafted `Sec-CH-UA-Model` header to an application that calls `UAParser(headers).withClientHints()`, an attacker can cause the parser to spend excessive CPU time due to catastrophic backtracking in the device [regex](https://github.com/faisalman/ua-parser-js/blob/2.0.9/src/main/ua-parser.js#L615):\n\n```js\n/ ([\\w ]+) miui\\/v?\\d/i\n```\n\nUnlike when using the `User-Agent` value, which has a hard limit of `UA_MAX_LENGTH = 500`, when using Client Hints, values are copied without a length limit before being passed into regex parsing.\n\n### PoC\n\n```js\nconst { UAParser } = require(\u0027ua-parser-js\u0027);\n\nconst headers = {\n \u0027sec-ch-ua-platform\u0027: \u0027\"Android\"\u0027,\n \u0027sec-ch-ua-mobile\u0027: \u0027?1\u0027,\n \u0027sec-ch-ua-model\u0027: \u0027\"\u0027 + \u0027A \u0027.repeat(25000) + \u0027\"\u0027\n};\n\nconst t0 = process.hrtime.bigint();\nUAParser(headers).withClientHints();\nconst ms = Number(process.hrtime.bigint() - t0) / 1e6;\n\nif (ms \u003e 100) {\n console.log(\u0027Potential ReDoS\u0027);\n}\n```\n\n### Impact\n\nThis vulnerability allows an unauthenticated attacker to trigger a denial-of-service condition in any __server-side__ application that uses `UAParser(headers).withClientHints()`. A single request with a ~32,000-character model value can consume over 400ms of CPU time, with parsing time growing polynomially with input length. The impact is __availability__ only, there is no confidentiality or integrity impact.\n\n### Affected Versions\n\n`ua-parser-js` versions `\u003e=2.0.1, \u003c=2.0.9` are affected. The `withClientHints()` API is not present in version `0.7.x` or `1.x`.\n\n### Patches\n\nA patch has been released to fix the vulnerable regular expression and limit the Client Hints input. Users should update to version `2.0.10` or later.\n\n### References\n\n- [Regular expression Denial of Service - ReDoS (OWASP)](https://owasp.org/www-community/attacks/Regular_expression_Denial_of_Service_-_ReDoS)\n\n### Credits\n\nThanks to [@sondt99](https://github.com/sondt99), who first reported the issue.",

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