### Impact In all Envoy Gateway versions prior to 1.2.7 and 1.3.1 a default Envoy Proxy access log configuration is used. This format is vulnerable to log injection attacks. If the attacker uses a specially crafted user-agent which performs json injection, then he could add and overwrite fields to the access log. Examples of attacks include: - Using following string as user agent : `HELLO-WORLD", "evil-ip": "1.1.1.1", "x-forwarded-for": "1.1.1.1` would lead to setting of new access log properties and overwrite of existing properties. Existing properties such as the value of the X-Forwarded-For header may have importance for security analysis of access logs, and their overwrite can be used to hide malicious activity. - Using the following string as user-agent : `"` which renders an invalid json document. The invalid document may fail to be processed by observability solutions, which would allow attacker to hide malicious activity. ### Patches 1.3.1, 1.2.7 ### Fix Using JSON ...
### Summary The API endpoint related to the password reset function is vulnerable to Reflected Cross-Site-Scripting. ### Details Throughout the source-code analysis, it has been found that the endpoint /api/v1/db/auth/password/reset/:tokenId is vulnerable to Reflected Cross-Site-Scripting. The flaw occurs due to implementation of the client-side template engine ejs, specifically on file resetPassword.ts where the template is using the insecure function “<%-“ https://github.com/nocodb/nocodb/blob/ba5a191b33259d984fc92df225f7d82ede2ddb56/packages/nocodb/src/modules/auth/ui/auth/resetPassword.ts#L71 which is rendered by the function renderPasswordReset: https://github.com/nocodb/nocodb/blob/ba5a191b33259d984fc92df225f7d82ede2ddb56/packages/nocodb/src/modules/auth/auth.controller.ts#L251 ### PoC Send the request below to a vulnerable instance: `/api/v1/db/auth/password/reset/asdsad%3C%2F%73%63%72%69%70%74%3E%3C%73%63%72%69%70%74%3E%61%6C%65%72%74%28%31%29%3C%2F%73%63%72%69%70%...
A DOM Clobbering vulnerability in tsup v8.3.4 allows attackers to execute arbitrary code via a crafted script in the import.meta.url to document.currentScript in cjs_shims.js components
Cross Site Scripting vulnerability in seajs v.2.2.3 allows a remote attacker to execute arbitrary code via the seajs package
## Goroutine Leak in Abacus SSE Implementation ### Summary A critical goroutine leak vulnerability has been identified in the Abacus server's Server-Sent Events (SSE) implementation. The issue occurs when clients disconnect from the `/stream` endpoint, as the server fails to properly clean up resources and terminate associated goroutines. This leads to resource exhaustion where the server continues running but eventually stops accepting new SSE connections while maintaining high memory usage. The vulnerability specifically involves improper channel cleanup in the event handling mechanism, causing goroutines to remain blocked indefinitely. ### [POC](https://github.com/JasonLovesDoggo/abacus/blob/main/docs/bugs/GHSA-vh64-54px-qgf8/test.py) ### Impact This vulnerability affects all versions of Abacus prior to v1.4.0. The issue causes: - Permanent unresponsiveness of the `/stream` endpoint after prolonged use - Memory growth that stabilizes at a high level but prevents proper functio...
Stage.js through 0.8.10 allows DOM Clobbering (with resultant XSS for untrusted input that contains HTML but does not directly contain JavaScript), because document.currentScript lookup can be shadowed by attacker-injected HTML elements.
Prism (aka PrismJS) through 1.29.0 allows DOM Clobbering (with resultant XSS for untrusted input that contains HTML but does not directly contain JavaScript), because document.currentScript lookup can be shadowed by attacker-injected HTML elements.
### Summary The site title field at /panel/options/site/allows embedding JS tags, which can be used to attack all members of the system. This is a widespread attack and can cause significant damage if there is a considerable number of users. ### Impact The attack is widespread, leveraging what XSS can do. This will undoubtedly impact system availability. ### Patches - [**Formwork 2.x** (aa3e9c6)](https://github.com/getformwork/formwork/commit/aa3e9c684035d9e8495169fde7c57d97faa3f9a2) escapes site title from panel header navigation. ### Details By embedding "<!--", the source code can be rendered non-functional, significantly impacting system availability. However, the attacker would need admin privileges, making the attack more difficult to execute. ### PoC  1. The page where the vulnerability was found, and the attack surface is the Title field. ) Affected versions: IBC-Go >= v7; Earlier IBC-Go versions may also be affected. Affected users: Validators, Full nodes, IBC Middleware authors ### Description An issue was discovered in IBC-Go's deserialization of acknowledgements that results in non-deterministic behavior which can halt a chain. Any user that can open an IBC channel can introduce this state to the chain ### Patches The new IBC-Go releases below address this issue: * [v7.9.2](https://github.com/cosmos/ibc-go/releases/tag/v7.9.2) * [v8.6.1](https://github.com/cosmos/ibc-go/releases/tag/v8.6.1) ### Workarounds To prevent this state from being introduced to a chain, it is possible to permission Channel Opening as a workaroun...
> [!NOTE] > This advisory was originally emailed to community@solidjs.com by @nsysean. To sum it up, the use of javascript's `.replace()` opens up to potential XSS vulnerabilities with the special replacement patterns beginning with `$`. Particularly, when the attributes of `Meta` tag from solid-meta are user-defined, attackers can utilise the special replacement patterns, either `$'` or `$\`` to achieve XSS. The solid-meta package has this issue since it uses `useAffect` and context providers, which injects the used assets in the html header. "dom-expressions" uses `.replace()` to insert the assets, which is vulnerable to the special replacement patterns listed above. This effectively means that if the attributes of an asset tag contained user-controlled data, it would be vulnerable to XSS. For instance, there might be meta tags for the open graph protocol in a user profile page, but if attackers set the user query to some payload abusing `.replace()`, then they could execute a...
