CWE-830
Inclusion of Web Functionality from an Untrusted Source
Extended description
Including third party functionality in a web-based environment is risky, especially if the source of the functionality is untrusted. Even if the third party is a trusted source, the product may still be exposed to attacks and malicious behavior if that trusted source is compromised, or if the code is modified in transmission from the third party to the product. This weakness is common in "mashup" development on the web, which may include source functionality from other domains. For example, Javascript-based web widgets may be inserted by using '<SCRIPT SRC="http://other.domain.here">' tags, which causes the code to run in the domain of the product, not the remote site from which the widget was loaded. As a result, the included code has access to the local DOM, including cookies and other data that the developer might not want the remote site to be able to access. Such dependencies may be desirable, or even required, but sometimes programmers are not aware that a dependency exists.

| CVE | Description | Severity | EPSS | Flags | Modified |
|---|---|---|---|---|---|
| CVE-2025-64496 | Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Versions 0.6.224 and prior contain a code injection vulnerability in the Direct Connections feature that allows malicious external model servers to execute arbitrary JavaScript in victim browsers via Server-Sent Event (SSE) execute events. This leads to authentication token theft, complete account takeover, and when chained with the Functions API, enables remote code execution on the backend server. The attack requires the victim to enable Direct Connections (disabled by default) and add the attacker's malicious model URL, achievable through social engineering of the admin and subsequent users. This issue is fixed in version 0.6.35. | HIGH8.0 | 7.60%p94 | 2025-11-26 | |
| CVE-2024-29944 | An attacker was able to inject an event handler into a privileged object that would allow arbitrary JavaScript execution in the parent process. Note: This vulnerability affects Desktop Firefox only, it does not affect mobile versions of Firefox. This vulnerability affects Firefox < 124.0.1 and Firefox ESR < 115.9.1. | HIGH8.4 | 4.70%p91 | 2025-04-01 | |
| CVE-2023-2588 | Teltonika’s Remote Management System versions prior to 4.10.0 have a feature allowing users to access managed devices’ local secure shell (SSH)/web management services over the cloud proxy. A user can request a web proxy and obtain a URL in the Remote Management System cloud subdomain. This URL could be shared with others without Remote Management System authentication . An attacker could exploit this vulnerability to create a malicious webpage that uses a trusted and certified domain. An attacker could initiate a reverse shell when a victim connects to the malicious webpage, achieving remote code execution on the victim device. | HIGH8.8 | 1.12%p62 | 2025-01-16 | |
| CVE-2021-28162 | In Eclipse Theia versions up to and including 0.16.0, in the notification messages there is no HTML escaping, so Javascript code can run. | MEDIUM6.1 | 0.78%p51 | 2024-11-21 | |
| CVE-2024-42381 | os/linux/elf.rb in Homebrew brew before 4.2.20 uses ldd to load ELF files obtained from untrusted sources, which allows attackers to achieve code execution via an ELF file with a custom .interp section. NOTE: this code execution would occur during an un-sandboxed binary relocation phase, which occurs before a user would expect execution of downloaded package content. (237d1e783f7ee261beaba7d3f6bde22da7148b0a was the tested vulnerable version.) | HIGH8.3 | 0.61%p44 | 2026-04-15 | |
| CVE-2025-33028 | In WinZip through 29.0, there is a Mark-of-the-Web Bypass Vulnerability because of an incomplete fix for CVE-2024-8811. This vulnerability allows attackers to bypass the Mark-of-the-Web protection mechanism on affected installations of WinZip. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the handling of archived files. When extracting files from a crafted archive that bears the Mark-of-the-Web, WinZip does not propagate the Mark-of-the-Web to the extracted files. An attacker can leverage this vulnerability to execute arbitrary code in the context of the current user. NOTE: a third party has reported that this is a false positive, and has observed that the original CVE-2025-33028.md file has been deleted on GitHub. Also, this is disputed because Mark-of-the-Web propagation can increase risk via security-warning habituation, and because the intended control sphere for file-origin metadata (e.g., HostUrl in Zone.Identifier) may be narrower than that for reading the file's content. | MEDIUM6.1 | 0.48%p37 | 2026-04-15 | |
| CVE-2024-35180 | OMERO.web provides a web based client and plugin infrastructure. There is currently no escaping or validation of the `callback` parameter that can be passed to various OMERO.web endpoints that have JSONP enabled. This vulnerability has been patched in version 5.26.0. | MEDIUM6.1 | 0.29%p21 | 2025-09-29 | |
| CVE-2025-46652 | In IZArc through 4.5, there is a Mark-of-the-Web Bypass Vulnerability. When a user performs an extraction from an archive file that bears Mark-of-the-Web, Mark-of-the-Web is not propagated to the extracted files. NOTE: this is disputed because Mark-of-the-Web propagation can increase risk via security-warning habituation, and because the intended control sphere for file-origin metadata (e.g., HostUrl in Zone.Identifier) may be narrower than that for reading the file's content. | MEDIUM6.1 | 0.26%p17 | 2026-04-15 | |
| CVE-2025-65109 | Minder is an open source software supply chain security platform. In Minder Helm version 0.20241106.3386+ref.2507dbf and Minder Go versions from 0.0.72 to 0.0.83, Minder users may fetch content in the context of the Minder server, which may include URLs which the user would not normally have access to. This issue has been patched in Minder Helm version 0.20250203.3849+ref.fdc94f0 and Minder Go version 0.0.84. | NONE | 0.24%p14 | 2026-04-15 | |
| CVE-2025-33027 | In Bandisoft Bandizip through 7.37, there is a Mark-of-the-Web Bypass Vulnerability. This vulnerability allows attackers to bypass the Mark-of-the-Web protection mechanism on affected installations of Bandizip. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the handling of archived files. When extracting files from a crafted archive that bears the Mark-of-the-Web, Bandizip does not propagate the Mark-of-the-Web to the extracted files. An attacker can leverage this vulnerability to execute arbitrary code in the context of the current user. NOTE: this is disputed because Mark-of-the-Web propagation can increase risk via security-warning habituation, and because the intended control sphere for file-origin metadata (e.g., HostUrl in Zone.Identifier) may be narrower than that for reading the file's content. | HIGH7.8 | 0.23%p14 | 2025-10-24 | |
| CVE-2025-33026 | In PeaZip through 10.4.0, there is a Mark-of-the-Web Bypass Vulnerability. This vulnerability allows attackers to bypass the Mark-of-the-Web protection mechanism on affected installations of PeaZip. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the handling of archived files. When extracting files from a crafted archive that bears the Mark-of-the-Web, PeaZip does not propagate the Mark-of-the-Web to the extracted files. An attacker can leverage this vulnerability to execute arbitrary code in the context of the current user.

| CVE-2025-43703 | An issue was discovered in Ankitects Anki through 25.02. A crafted shared deck can result in attacker-controlled access to the internal API (even though the attacker has no knowledge of an API key) through approaches such as scripts or the SRC attribute of an IMG element. NOTE: this issue exists because of an incomplete fix for CVE-2024-32484. | MEDIUM5.4 | 0.19%p9 | 2025-10-09 |
