Descripción técnica

Axios is a promise based HTTP client for the browser and Node.js. Prior to 1.15.1 and 0.31.1, when Object.prototype has been polluted by any co-dependency with keys that axios reads without a hasOwnProperty guard, an attacker can (a) silently intercept and modify every JSON response before the application sees it, or (b) fully hijack the underlying HTTP transport, gaining access to request credentials, headers, and body. The precondition is prototype pollution from a separate source in the same process. This vulnerability is fixed in 1.15.1 and 0.31.1.

——28Improperly Controlled Modification of Dynamically-Determined Object Attributes vulnerability in Apache Camel Camel-Coap component. Apache Camel's camel-coap component is vulnerable to Camel message header injection, leading to remote code execution when routes forward CoAP requests to header-sensitive producers (e.g. camel-exec) The camel-coap component maps incoming CoAP request URI query parameters directly into Camel Exchange In message headers without applying any HeaderFilterStrategy. Specifically, CamelCoapResource.handleRequest() iterates over OptionSet.getUriQuery() and calls camelExchange.getIn().setHeader(...) for every query parameter. CoAPEndpoint extends DefaultEndpoint rather than DefaultHeaderFilterStrategyEndpoint, and CoAPComponent does not implement HeaderFilterStrategyComponent; the component contains no references to HeaderFilterStrategy at all. As a result, an unauthenticated attacker who can send a single CoAP UDP packet to a Camel route consuming from coap:// can inject arbitrary Camel internal headers (those prefixed with Camel*) into the Exchange. When the route delivers the message to a header-sensitive producer such as camel-exec, camel-sql, camel-bean, camel-file, or template components (camel-freemarker, camel-velocity), the injected headers can alter the producer's behavior. In the case of camel-exec, the CamelExecCommandExecutable and CamelExecCommandArgs headers override the executable and arguments configured on the endpoint, resulting in arbitrary OS command execution under the privileges of the Camel process. The producer's output is written back to the Exchange body and returned in the CoAP response payload by CamelCoapResource, giving the attacker an interactive RCE channel without any need for out-of-band exfiltration. Exploitation prerequisites are minimal: a single unauthenticated UDP datagram to the CoAP port (default 5683). CoAP (RFC 7252) has no built-in authentication, and DTLS is optional and disabled by default. Because the protocol is UDP-based, HTTP-layer WAF/IDS controls do not apply. This issue affects Apache Camel: from 4.14.0 through 4.14.5, from 4.18.0 before 4.18.1, 4.19.0. Users are recommended to upgrade to version 4.18.1 or 4.19.0, fixing the issue.2d CVE-2021-288609.1 CRÍ

——23In Node.js mixme, prior to v0.5.1, an attacker can add or alter properties of an object via '__proto__' through the mutate() and merge() functions. The polluted attribute will be directly assigned to every object in the program. This will put the availability of the program at risk causing a potential denial of service (DoS).8d CVE-2026-401754.8 MED

——23Axios is a promise based HTTP client for the browser and Node.js. Versions prior to 1.15.0 and 0.3.1 are vulnerable to a specific gadget-style attack chain in which prototype pollution in a third-party dependency may be leveraged to inject unsanitized header values into outbound requests. This vulnerability is fixed in 1.15.0 and 0.3.1.2d CVE-2025-134655.3 MED

——22Lodash versions 4.0.0 through 4.17.22 are vulnerable to prototype pollution in the _.unset and _.omit functions. An attacker can pass crafted paths which cause Lodash to delete methods from global prototypes. The issue permits deletion of properties but does not allow overwriting their original behavior.
