### Impact This vulnerability only affects users of the AWS attestor. Users of the AWS attestor could have unknowingly received a forged identity document. While this may seem unlikely, AWS recently issued a security bulletin about IMDS (Instance Metadata Service) impersonation.[^1] There are multiple locations where the verification of the identity document will mistakenly report a successful verification. - If a signature is not present or is empty https://github.com/in-toto/go-witness/blob/0c8bb30c143951d88b1d4b32f260c5f67d30137b/attestation/aws-iid/aws-iid.go#L161-L163 - If the RSA verification of the document fails for any reason https://github.com/in-toto/go-witness/blob/0c8bb30c143951d88b1d4b32f260c5f67d30137b/attestation/aws-iid/aws-iid.go#L192-L196 ### Workarounds The contents of the AWS attestation contain the identity document, signature, and public key that was used to verify the document. These attestations and their could be identity documents could be manually verif...

### Impact The OpenSearch sink and source plugins in Data Prepper are configured to trust all SSL certificates by default when no certificate path was provided, making connections vulnerable to man-in-the-middle attacks. Prior to this fix, the OpenSearch sink and source plugins would automatically use a trust all SSL strategy when connecting to OpenSearch clusters if no certificate path was explicitly configured. This behavior bypassed SSL certificate validation, potentially allowing attackers to intercept and modify data in transit through man-in-the-middle attacks. The vulnerability affects connections to OpenSearch when the `cert` parameter is not explicitly provided. ### Patches Data Prepper 2.12.2 ### Workarounds If you cannot immediately upgrade to the fixed version, you can implement the following workaround. #### OpenSearch sink Add the `cert` parameter to your OpenSearch sink configuration with the path to your cluster's CA certificate. The following example shows how...

### Summary `sveltekit-superforms` v2.27.3 and prior are susceptible to a prototype pollution vulnerability within the `parseFormData` function of `formData.js`. An attacker can inject string and array properties into `Object.prototype`, leading to denial of service, type confusion, and potential remote code execution in downstream applications that rely on polluted objects. ### Details Superforms is a SvelteKit form library for server and client form validation. Under normal operation, form validation is performed by calling the the `superValidate` function, with the submitted form data and a form schema as arguments: ```js // https://superforms.rocks/get-started#posting-data const form = await superValidate(request, your_adapter(schema)); ``` Within the `superValidate` function, a call is made to `parseRequest` in order to parse the user's input. `parseRequest` then calls into `parseFormData`, which in turn looks for the presence of `__superform_json` in the form parameters. If `_...

### Summary An HTML injection vulnerability in plaintext emails generated by Mailgen has been discovered. Projecta are affected if the `Mailgen.generatePlaintext(email)` method is used and passed in user-generated content. The issue was discovered and reported by Edoardo Ottavianelli (@edoardottt). ### Details The following function (inside index.js) is intended to strip all HTML content to produce a plaintext string. ```javascript // Plaintext text e-mail generator Mailgen.prototype.generatePlaintext = function (params) { // Plaintext theme not cached? if (!this.cachedPlaintextTheme) { throw new Error('An error was encountered while loading the plaintext theme.'); } // Parse email params and get back an object with data to inject var ejsParams = this.parseParams(params); // Render the plaintext theme with ejs, injecting the data accordingly var output = ejs.render(this.cachedPlaintextTheme, ejsParams); // Definition of the <br /> tag ...

F5 disclosed a breach this week that included zero-day bugs, source code, and some customer information.

### Impact During deserialization of ECDSA and EdDSA signatures gnark-crypto did not check that the values are in the range `[1, n-1]` with `n` being the corresponding modulus (either base field modulus in case of `R` in EdDSA, and scalar field modulus in case of `s,r` in ECDSA and `s` in EdDSA). As this also allowed zero inputs, then it was possible to craft a signature which lead to null pointer dereference, leading to denial-of-service of an application. This also enabled weak signature malleability when the users assumed uniqueness of the serialized signatures (but not the underlying modulo reduced values). We are not aware of any users impacted by the bug. The implemented signature schemes in gnark-crypto complement the in-circuit versions in gnark, allowing to have end-to-end tests. ### Patches The issue was patched in PR #449. The fix returns an error during deserialization if the values do not belong to the ranges `[1, n-1]`. The fix is included in release v0.12.0 and upwa...

### Mitigation Make sure `GITHUB_CODESPACES_PORT_FORWARDING_DOMAIN` is not set in a production environment. So the following is correct: ``` assert os.getenv("GITHUB_CODESPACES_PORT_FORWARDING_DOMAIN") is None ``` ### **Vulnerability Description** --- **Vulnerability Overview** - When the GET /auth-codespace page loads in a GitHub Codespaces environment, it automatically assigns the redirect_to query parameter value directly to client-side links without any validation and triggers automatic clicks. This allows attackers to redirect users to arbitrary external URLs. - The route is only registered when a Codespaces environment is detected, and the detection is controlled by environment variables. This means that the same behavior can be activated in production if the corresponding environment variable is set. **Vulnerable Code Analysis** https://github.com/reflex-dev/reflex/blob/51f9f2c2f52cac4d66c07683a12bc0237311b6be/reflex/utils/codespaces.py#L18-L46 - This code assigns th...
