GHSA-JXHC-Q857-3J6G
Vulnerability from github – Published: 2021-07-12 16:58 – Updated: 2026-04-06 23:12Impact
Within the URI template implementation in Addressable, a maliciously crafted template may result in uncontrolled resource consumption, leading to denial of service when matched against a URI. In typical usage, templates would not normally be read from untrusted user input, but nonetheless, no previous security advisory for Addressable has cautioned against doing this. Users of the parsing capabilities in Addressable but not the URI template capabilities are unaffected.
Patches
The vulnerability was introduced in version 2.3.0 (previously yanked) and has been present in all subsequent versions up to, and including, 2.7.0. It is fixed in version 2.8.0.
Workarounds
The vulnerability can be avoided by only creating Template objects from trusted sources that have been validated not to produce catastrophic backtracking.

Vulnerability from github – Published: 2026-05-18 16:22 – Updated: 2026-06-09 10:32The max option was being applied too late:
When expanding a single large numeric range like {1..10000000}, the sequence generation loop generates all 10 million intermediate elements before the max limit is applied With max=10, the output is correctly limited to 10 items, but the process still allocates ~505 MB and spends ~800ms building the full intermediate array.

Ensure the string to be expanded doesn't contain more values than the desired max item count.

GHSA-M284-85MF-CGRC
Vulnerability from github – Published: 2023-09-13 16:31 – Updated: 2023-09-13 16:31Summary
Field level permissions not being respected in relationship title. If I have a relationship title and the relationship shows a field I don't have permission to see I will still be visible.
Details
No RBAC checks on on the relationship the relation endpoint returns
PoC
Setup
Create a fresh strapi instance Create a new content type in the newly created content type add a relation to the users-permissions user. Save. Create a users-permissions user Use your created content type and create an entry in it related to the users-permisisons user
Go to settings -> Admin panel -> Roles -> Author Give the author role full permissions on the content type your created. Make sure they don't have any permission to see User Save
Create a new admin account with only the author role
CVE
login on the newly created author acount. go to the content manager to the colection type you created with the relationship to users_permissions_user You now see a field you don't have permissions to view.
Impact
RBAC field level checks leaks data selected by the admin user as relationship title What could be sensitive fields that they should not be allowed to see. by the person having this specific role.

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.
