Consul and Consul Enterprise’s (“Consul”) event endpoint is vulnerable to denial of service (DoS) due to lack of maximum value on the Content Length header. This vulnerability, CVE-2025-11375, is fixed in Consul Community Edition 1.22.0 and Consul Enterprise 1.22.0, 1.21.6, 1.20.8 and 1.18.12.

Consul and Consul Enterprise’s (“Consul”) key/value endpoint is vulnerable to denial of service (DoS) due to incorrect Content Length header validation. This vulnerability, CVE-2025-11374, is fixed in Consul Community Edition 1.22.0 and Consul Enterprise 1.22.0, 1.21.6, 1.20.8 and 1.18.12.

### Summary An unauthenticated attacker can send a crafted HTTP Range header that triggers quadratic-time processing in Starlette's `FileResponse` Range parsing/merging logic. This enables CPU exhaustion per request, causing denial‑of‑service for endpoints serving files (e.g., `StaticFiles` or any use of `FileResponse`). ### Details Starlette parses multi-range requests in ``FileResponse._parse_range_header()``, then merges ranges using an O(n^2) algorithm. ```python # starlette/responses.py _RANGE_PATTERN = re.compile(r"(\d*)-(\d*)") # vulnerable to O(n^2) complexity ReDoS class FileResponse(Response): @staticmethod def _parse_range_header(http_range: str, file_size: int) -> list[tuple[int, int]]: ranges: list[tuple[int, int]] = [] try: units, range_ = http_range.split("=", 1) except ValueError: raise MalformedRangeHeader() # [...] ranges = [ ( int(_[0]) if _[0] else file_size - in...

About Remote Code Execution – Redis “RediShell” (CVE-2025-49844) vulnerability. Redis is a popular in-memory key–value database, used as a distributed cache and message broker, with optional durability. This vulnerability allows a remote authenticated attacker to execute arbitrary code via a specially crafted Lua script. The requirement for authentication does not reduce its severity, because authentication […]

### Summary A malicious host may provide a crafted LUKS2 volume to a Contrast pod VM that uses the [secure persistent volume](https://docs.edgeless.systems/contrast/howto/encrypted-storage) feature. The guest will open the volume and write secret data using a volume key known to the attacker. LUKS2 volume metadata is (a) not authenticated and (b) supports null key-encryption algorithms, allowing an attacker to create a volume such that the volume: - Opens (cryptsetup open) without error using any passphrase or token - Records all writes in plaintext (or ciphertext with an attacker-known key) ### Details Contrast uses cryptsetup to setup secure persistent volumes, using the secret seed as key for the cryptsetup encryption. To do so the Contrast Initializer will invoke the `cryptsetup` CLI. If the device provided by Kubernetes is a identified as cryptsetup device, the Initializer assumes a pod restart happened and the device was previously encrypted with the secret seed. The Initia...

### Impact Any plugin using a GUI with the GuiStorageElement and allows taking out items out of that element. ### Patches InventoryGui 1.6.5 (included in latest 1.6.5-SNAPSHOT) by disabling GuiStorageElement when not running on 1.21.9 or later. ### Workarounds Not using the GuiStorageElement.

Cybersecurity researchers have disclosed details of a new Android banking trojan called Herodotus that has been observed in active campaigns targeting Italy and Brazil to conduct device takeover (DTO) attacks. "Herodotus is designed to perform device takeover while making first attempts to mimic human behaviour and bypass behaviour biometrics detection," ThreatFabric said in a report shared with

A flaw was found in Keycloak. In Keycloak where a user can accidentally get access to another user's session if both use the same device and browser. This happens because Keycloak sometimes reuses session identifiers and doesn’t clean up properly during logout when browser cookies are missing. As a result, one user may receive tokens that belong to another user.

A global deal to fight cybercrime sounds sensible—but critics warn it could expand surveillance and criminalize researchers.
