### Summary Due to the insufficient patch for the CVE-2024-39931, it's still possible to delete files under the `.git` directory and achieve remote command execution. ### Details In the patch for CVE-2024-39931, the following check is added: https://github.com/gogs/gogs/commit/77a4a945ae9a87f77e392e9066b560edb71b5de9 ```diff + // 🚨 SECURITY: Prevent uploading files into the ".git" directory + if isRepositoryGitPath(opts.TreePath) { + return errors.Errorf("bad tree path %q", opts.TreePath) + } ``` While the above code snippet checks if the specified path is a `.git` directory, there are no checks for symbolic links in the later steps. So, by creating a symbolic link that points to the `.git` directory, an attacker can still delete arbitrary files in the `.git` directory and achieve remote command execution. ### Impact Unprivileged user accounts can execute arbitrary commands on the Gogs instance with the privileges of the account specified by `RUN_USER` in the configuration. It a...

### Summary On historic but declared as supported Node.js versions (0.12-2.x), pbkdf2 silently disregards Uint8Array input This only affects Node.js <3.0.0, but `pbkdf2` claims to: * Support Node.js [>= 0.12](https://github.com/browserify/pbkdf2/blob/v3.1.2/package.json#L62) (and there seems to be ongoing effort in this repo to maintain that) * Support `Uint8Array` input (input is typechecked against Uint8Array, and the error message includes e.g. "Password must be a string, a Buffer, a typed array or a DataView" ### Details The error is in `toBuffer` method This vulnerability somehow even made it to tests: https://github.com/browserify/pbkdf2/commit/eb9f97a66ed83836bebc4ff563a1588248708501 There, `resultsOld` (where mismatch `results`) are just invalid output generated from empty password/salt instead of the supplied one ### PoC On Node.js/io.js < 3.0.0 ```console > require('pbkdf2').pbkdf2Sync(new Uint8Array([1,2,3]), new Uint8Array([1,3,4]), 1024, 32, 'sha256') <Buffer 21 ...

### Summary This affects both: 1. Unsupported algos (e.g. `sha3-256` / `sha3-512` / `sha512-256`) 2. Supported but non-normalized algos (e.g. `Sha256` / `Sha512` / `SHA1` / `sha-1` / `sha-256` / `sha-512`) All of those work correctly in Node.js, but this polyfill silently returns highly predictable ouput Under Node.js (only with `pbkdf2/browser` import, unlikely) / Bun (`pbkdf2` top-level import is affected), the memory is not zero-filled but is uninitialized, as `Buffer.allocUnsafe` is used Under browsers, it just returns zero-filled buffers (Which is also critical, those are completely unacceptable as kdf output and ruin security) ### Were you affected? The full list of arguments that were **not** affected were literal: * `'md5'` * `'sha1'` * `'sha224'` * `'sha256'` * `'sha384'` * `'sha512'` * `'rmd160'` * `'ripemd160'` Any other arguments, e.g. representation variations of the above ones like `'SHA-1'`/`'sha-256'`/`'SHA512'` or different algos like `'sha3-512'`/`'b...

A Server-Side Request Forgery (SSRF) vulnerability exists in the RequestsToolkit component of the langchain-community package (specifically, langchain_community.agent_toolkits.openapi.toolkit.RequestsToolkit) in langchain-ai/langchain version 0.0.27. This vulnerability occurs because the toolkit does not enforce restrictions on requests to remote internet addresses, allowing it to also access local addresses. As a result, an attacker could exploit this flaw to perform port scans, access local services, retrieve instance metadata from cloud environments (e.g., Azure, AWS), and interact with servers on the local network. This issue has been fixed in version 0.0.28.

### Impact Vert.x 4.5.12 has changed the semantics of the duplication of duplicated context. Duplicated context is an object used to propagate data through a processing (synchronous or asynchronous). Each "transaction" or "processing" runs on its own isolated duplicated context. Initially, duplicating a duplicated context was creating a fresh (empty) new context, meaning that the new duplicated context can be used to managed a separated transaction. In Vert.x 4.5.12, this semantics has changed, and since the content of the parent duplicated context is copied into the new one, potentially leaking data. This CVE is especially for Quarkus as Quarkus extensively uses the Vert.x duplicated context to implement context propagation. With the new semantic data from one transaction can leak to the data from another transaction. From a Vert.x point of view, this new semantic clarifies the behavior. A significant amount of data is stored in the duplicated context, including request scope,...
