GHSA-G8VQ-V3MG-7MRG
Vulnerability from github – Published: 2025-03-21 15:26 – Updated: 2025-03-21 15:26A vulnerability has been identified in Redlib where an attacker can cause a denial-of-service (DOS) condition by submitting a specially crafted base2048-encoded DEFLATE decompression bomb to the restore_preferences form. This leads to excessive memory consumption and potential system instability, which can be exploited to disrupt Redlib instances. This vulnerability was introduced in 2e95e1fc6e2064ccfae87964b4860bda55eddb9a and fixed in 15147cea8e42f6569a11603d661d71122f6a02dc.
Impact
What kind of vulnerability is it? Who is impacted?
This vulnerability allows a remote attacker with network access to exploit the preference restoration mechanism by providing a compressed payload that expands dramatically upon decompression. The issue arises because the system automatically decompresses user-supplied data without enforcing size limits, potentially leading to:
- Out-of-memory (OOM) conditions
- OS-level resource exhaustion, potentially leading to broader system instability or crashes
- Repeated exploitation, keeping the target system in a persistent degraded state
- Denial-of-service of any public instance
Patches
The problem has been patched in 15147cea8e42f6569a11603d661d71122f6a02dc. Users should upgrade to v0.36.0.
Workarounds
Until a patch is available, users can:
- Implement request size limits at the web server or application level to reject excessively large inputs.
- Disable or restrict the restore_preferences route (
/settings/encoded-restore) at the reverse-proxy level if not required. - Monitor server logs for unusually large or repeated restore_preferences requests and block offending IPs.

GHSA-G8WW-46X2-2P65
Vulnerability from github – Published: 2021-05-05 19:48 – Updated: 2023-08-08 15:37Impact
There is a possible Denial of Service vulnerability in Action Dispatch. Carefully crafted Accept headers can cause the mime type parser in Action Dispatch to do catastrophic backtracking in the regular expression engine.
Releases
The fixed releases are available at the normal locations.
Workarounds
The following monkey patch placed in an initializer can be used to work around the issue.
module Mime
class Type
MIME_REGEXP = /\A(?:\*\/\*|#{MIME_NAME}\/(?:\*|#{MIME_NAME})(?>\s*#{MIME_PARAMETER}\s*)*)\z/
end
end
Patches
To aid users who aren't able to upgrade immediately we have provided patches for the two supported release series. They are in git-am format and consist of a single changeset.
- 6-0-Prevent-catastrophic-backtracking-during-mime-parsin.patch - Patch for 6.0 series
- 6-1-Prevent-catastrophic-backtracking-during-mime-parsin.patch - Patch for 6.1 series
Please note that only the 6.1.Z, 6.0.Z, and 5.2.Z series are supported at present. Users of earlier unsupported releases are advised to upgrade as soon as possible as we cannot guarantee the continued availability of security fixes for unsupported releases.

GHSA-G95C-2JGM-HQC6
Vulnerability from github – Published: 2023-07-18 19:22 – Updated: 2023-07-18 19:22Impact
The Fides webserver is vulnerable to a type of Denial of Service (DoS) attack. Attackers can exploit a weakness in the connector template upload feature to upload a malicious zip bomb file, resulting in resource exhaustion and service unavailability for all users of the Fides webserver.
This vulnerability affects Fides versions 2.11.0 through 2.15.1. Exploitation is limited to users with elevated privileges with the CONNECTOR_TEMPLATE_REGISTER scope, which includes root users and users with the owner role.
Patches
The vulnerability has been patched in Fides version 2.16.0. Users are advised to upgrade to this version or later to secure their systems against this threat.
Workarounds
There is no known workaround to remediate this vulnerability without upgrading. If an attack occurs, the impact can be mitigated by manually or automatically restarting the affected container.

Vulnerability from github – Published: 2019-06-06 15:30 – Updated: 2026-02-03 17:47Duplicate Advisory
This advisory has been withdrawn because it is a duplicate of GHSA-cwfw-4gq5-mrqx. This link is maintained to preserve external references.
Original Description
Versions of braces prior to 2.3.1 are vulnerable to Regular Expression Denial of Service (ReDoS). Untrusted input may cause catastrophic backtracking while matching regular expressions. This can cause the application to be unresponsive leading to Denial of Service.
Recommendation
Upgrade to version 2.3.1 or higher.

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.
