Summary
justhtml introduces denial-of-service hardening
Details
Summary
justhtml 1.18.0 fixes multiple low-severity denial-of-service hardening issues in CSS selector handling and linkification.
These issues are availability concerns. They do not allow script execution, data disclosure, or sanitizer bypass by themselves.
Affected versions
justhtml< 1.18.0
Fixed version
justhtml1.18.0released on May 4, 2026
Impact
CSS selector handling
Applications that evaluate attacker-controlled selector strings, or that run selector-based transform pipelines over attacker-controlled documents, could consume disproportionate CPU or memory.
The affected selector patterns included oversized selectors, large selector lists, oversized compound selectors, long combinator chains, deeply nested functional pseudo-classes such as :not(...), repeated attribute/class token matching over large values, repeated sibling or ancestor scans, repeated positional pseudo-class work, and :contains(...) over large descendant text.
Programmatically constructed malformed DOM graphs could also trigger non-terminating or duplicate traversal in some selector paths, including cyclic/shared child graphs, cyclic parent chains, and cyclic text traversal for :contains(...).
Linkification
Attacker-controlled text containing punctuation-heavy input or URL candidates ending in long runs of unmatched closing brackets could cause repeated rescanning and consume disproportionate CPU when linkification was enabled.
Default configuration
Ordinary sanitization of parsed HTML with the default JustHTML(..., sanitize=True) configuration is not expected to expose untrusted users to selector injection, because selectors are normally supplied by application code.
The main risk areas are:
- applications that accept selector strings from untrusted users and pass them to
query(...),matches(...), or selector-based transforms - custom transform or sanitization pipelines that run selector matching over very large untrusted documents
- applications that construct or mutate DOM trees programmatically from untrusted structure
- applications that enable
Linkify(...)over attacker-controlled text
Fixes in 1.18.0
1.18.0 adds generalized selector resource controls and removes several repeated-work hot paths:
- shared selector limits for parse and match operations
- structural caps for selector length, selector lists, compound selectors, complex selectors, and parse depth
- match-operation and string-byte budgets
- per-query matcher state for caches and cycle guards
- precomputed or cached ancestor, sibling, positional, attribute-token, text-content,
:not(...),:empty, and:nth-child(...)work - consistent enforcement across public parsing,
query(...), tag-only query fast paths, transform selector compilation, and sanitization transform matching - linkification hardening for punctuation-heavy inputs and trailing bracket trimming
CWE mapping
- CWE-400: Uncontrolled Resource Consumption
- CWE-407: Inefficient Algorithmic Complexity
- CWE-835: Loop with Unreachable Exit Condition
Recommended action
Upgrade to justhtml 1.18.0.
If users cannot upgrade immediately:
- do not pass untrusted selector strings to
query(...),matches(...), or selector-based transforms - restrict the size of untrusted documents before selector matching or linkification
- avoid constructing programmatic DOM graphs from untrusted structure
- avoid enabling
Linkify(...)on very large attacker-controlled text

Summary
.NET Denial of Service Vulnerability
Details
Microsoft is releasing this security advisory to provide information about a vulnerability in .NET Core 3.1 and .NET 6.0. This advisory also provides guidance on what developers can do to update their applications to remove this vulnerability.
A denial of service vulnerability exists in ASP.NET Core 3.1 and .NET 6.0 where a malicious client could cause a stack overflow which may result in a denial of service attack when an attacker sends a customized payload that is parsed during model binding.
Affected software
- Any .NET 6.0 application running on .NET 6.0.8 or earlier.
- Any ASP.NET Core 3.1 application running on .NET Core 3.1.28 or earlier. If your application uses the following package versions, ensure you update to the latest version of .NET.
.NET Core 3.1

Summary
Authorino Uncontrolled Resource Consumption vulnerability
Details
The Authorino service in the Red Hat Connectivity Link is the authorization service for zero trust API security. Authorino allows the users with developer persona to add callbacks to be executed to HTTP endpoints once the authorization process is completed. It was found that an attacker with developer persona access can add a large number of those callbacks to be executed by Authorino and as the authentication policy is enforced by a single instance of the service, this leada to a Denial of Service in Authorino while processing the post-authorization callbacks.

Mitigation
Architecture and Design
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
Architecture and Design
- 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
Architecture and Design
Ensure that protocols have specific limits of scale placed on them.
Mitigation
Implementation
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.
