#xss

Cross-site scripting (XSS) vulnerability in the [clickstorm] SEO (cs_seo) TYPO3 extension allows backend users to execute arbitrary script via the JSON-LD output.

### Impact Rendering `{{ attributes }}` or using any method that returns a `ComponentAttributes` instance (e.g. `only()`, `defaults()`, `without()`) ouputs attribute values directly without escaping. If these values are unsafe (e.g. contain user input), this can lead to HTML attribute injection and XSS vulnerabilities. ### Patches The issue is fixed in version `2.25.1` of `symfony/ux-twig-component` by using Twig's `EscaperRuntime` to properly escape HTML attributes in `ComponentAttributes`. If you use `symfony/ux-live-component`, you must also update it to `2.25.1` to benefit from the fix, as it reuses the `ComponentAttributes` class internally. ### Workarounds Until you can upgrade, avoid rendering `{{ attributes }}` or derived objects directly if it may contain untrusted values. Instead, use `{{ attributes.render('name') }}` for safe output of individual attributes. ### References GitHub repository: [symfony/ux](https://github.com/symfony/ux)

A cyber-espionage campaign is targeting Ukrainian government entities with a series of sophisticated spear-phishing attacks that exploit XSS vulnerabilities.

### LibreNMS v25.4.0 suffers from Stored Cross-Site Scripting (XSS) Vulnerability in the 'group name' parameter of the 'http://localhost/poller/groups' form. This vulnerability allows attackers to inject malicious scripts into web pages viewed by other users. ## ---------------------------------POC----------------------------- Before Setting: Enable 'distributed_poller' in http://localhost/settings/poller/distributed 1. Attacker creates a new poller group and injects the payload in the 'group name' parameter ``` payload: <script>alert('XSS')</script> ``` 2. Victim navigates to the 'http://localhost/addhost' to add a new host 3. The payload is executed code sink: https://github.com/librenms/librenms/blob/25.4.0/includes/html/pages/addhost.inc.php#L284

The tarteaucitron-wp WordPress plugin before 0.3.0 allows author level and above users to add HTML into a post/page, which could allow users with the contributor role and above to perform Stored Cross-Site Scripting attacks.

### Summary The vulnerability allows an attacker to inject a malicious script into the context of a web page, which can lead to data theft, unauthorized actions on behalf of the user, and other attacks. ### Details The vulnerability is reproducible when sending a properly formatted request to the `POST /projects/upload-example/` endpoint. In the source code, the vulnerability is located at `label_studio/projects/views.py`. ```python 39: @require_http_methods(['POST']) 40: def upload_example_using_config(request): 41: """Generate upload data example by config only""" 42: config = request.POST.get('label_config', '') 43: 44: org_pk = get_organization_from_request(request) 45: secure_mode = False 46: if org_pk is not None: 47: org = generics.get_object_or_404(Organization, pk=org_pk) 48: secure_mode = org.secure_mode 49: 50: try: 51: Project.validate_label_config(config) 52: task_data, _, _ = get_sample_task(config, secure_mode) 5...

A Russia-linked threat actor has been attributed to a cyber espionage operation targeting webmail servers such as Roundcube, Horde, MDaemon, and Zimbra via cross-site scripting (XSS) vulnerabilities, including a then-zero-day in MDaemon, according to new findings from ESET. The activity, which commenced in 2023, has been codenamed Operation RoundPress by the Slovak cybersecurity company. It has

### Summary Stored Cross-Site Scripting (XSS) vulnerability allows attackers to inject malicious scripts into web applications, which can then be executed in the context of other users' browsers. This can lead to unauthorized access to sensitive information, session hijacking, and spreading of malware, impacting user data privacy and application integrity. ### Details A user with rights to modificate the service (e.g. kuiperUser role) can inject XSS Payload into Connection Configuration key `Name` (`confKey`) parameter. Then, after any user with access to this service (e.g. admin) will try to delete this key, a payload will act in victim's browser. ### PoC 1. Authorize as a user with rights to modificate the service (e.g. kuiperUser role). 2. Create a service or go to the existing one and access the *Configuration > Connection* page:  3. Open any existing Connection a...
