A critical misconfiguration in Amazon Web Services (AWS) CodeBuild could have allowed complete takeover of the cloud service provider's own GitHub repositories, including its AWS JavaScript SDK, putting every AWS environment at risk. The vulnerability has been codenamed CodeBreach by cloud security company Wiz. The issue was fixed by AWS in September 2025 following responsible disclosure on

In this week’s newsletter, Martin examines the evolving landscape for 2026, highlighting key threats, emerging trends like AI-driven risks, and the continued importance of addressing familiar vulnerabilities.

Aimeos 2021.10 LTS contains a SQL injection vulnerability in the json api 'sort' parameter that allows attackers to inject malicious database queries. Attackers can manipulate the sort parameter to reveal table and column names by sending crafted GET requests to the jsonapi/review endpoint.

## Summary The experimental `form` remote function uses a binary data format containing a representation of submitted form data. A specially-crafted payload can cause the server to allocate a large amount of memory, causing DoS via memory exhaustion. ## Details When a form is submitted to a remote function endpoint, the SvelteKit client encodes the data using a custom format, and POSTs it to the endpoint as a request with an `application/x-sveltekit-formdata` content type. The first few bytes of the request body encode the length of the data. SvelteKit will attempt to read the request body up until the specified offset, but if the body is not yet available then an array buffer of that size will be created eagerly to accommodate it as it arrives. An attacker can force this code path by sending a small payload that specifies a large data length, then stalling the connection. The resulting array buffer will be held in memory, potentially causing memory exhaustion. ## Impact - Vulne...

## Summary Certain inputs can cause `devalue.parse` to consume excessive CPU time and/or memory, potentially leading to denial of service in systems that parse input from untrusted sources. This affects applications using `devalue.parse` on externally-supplied data. The root cause is the typed array hydration expecting an `ArrayBuffer` as input, but not checking the assumption before creating the typed array. ## Details The parser's typed array hydration logic does not properly validate input before processing. Specially crafted inputs can cause disproportionate memory allocation or CPU usage on the receiving system. ## Impact This is a denial of service vulnerability affecting systems that use `devalue.parse` to handle data from potentially untrusted sources. Affected systems should upgrade to patched versions immediately.

### Summary Versions of SvelteKit are vulnerable to a server side request forgery (SSRF) and denial of service (DoS) under certain conditions. ### Details Affected versions from 2.44.0 onwards are vulnerable to DoS if: - your app has at least one prerendered route (`export const prerender = true`) Affected versions from 2.19.0 onwards are vulnerable to DoS and SSRF if: - your app has at least one prerendered route (`export const prerender = true`) - AND you are using `adapter-node` without a configured `ORIGIN` environment variable, and you are not using a reverse proxy that implements Host header validation ### Impact The DoS causes the running server process to end. The SSRF allows access to internal services that can be reached without authentication when fetched from SvelteKit's server runtime. It is also possible to obtain an SXSS via cache poisoning, by forcing a potential CDN to cache an XSS returned by the attacker's server (the latter being able to specify the cache-...

ANY.RUN report reveals how the new CastleLoader malware targets US government agencies using stealthy ClickFix tricks and memory-based attacks to bypass security.

### Impact Attempting to parse a patch whose filename headers contain the line break characters `\r`, `\u2028`, or `\u2029` can cause the `parsePatch` method to enter an infinite loop. It then consumes memory without limit until the process crashes due to running out of memory. Applications are therefore likely to be vulnerable to a denial-of-service attack if they call `parsePatch` with a user-provided patch as input. A large payload is not needed to trigger the vulnerability, so size limits on user input do not provide any protection. Furthermore, some applications may be vulnerable even when calling `parsePatch` on a patch generated by the application itself if the user is nonetheless able to control the filename headers (e.g. by directly providing the filenames of the files to be diffed). The `applyPatch` method is similarly affected if (and only if) called with a string representation of a patch as an argument, since under the hood it parses that string using `parsePatch`. Othe...

### Impact The `fetch()` API supports chained HTTP encoding algorithms for response content according to RFC 9110 (e.g., Content-Encoding: gzip, br). This is also supported by the undici decompress interceptor. However, the number of links in the decompression chain is unbounded and the default maxHeaderSize allows a malicious server to insert thousands compression steps leading to high CPU usage and excessive memory allocation. ### Patches Upgrade to 7.18.2 or 6.23.0. ### Workarounds It is possible to apply an undici interceptor and filter long `Content-Encoding` sequences manually. ### References * https://hackerone.com/reports/3456148 * https://github.com/advisories/GHSA-gm62-xv2j-4w53 * https://curl.se/docs/CVE-2022-32206.html
