### Impact An attacker who uses this vulnerability can craft a PDF which leads to large memory usage. This requires parsing the content stream of a page using the LZWDecode filter. ### Patches This has been fixed in [pypdf==6.1.3](https://github.com/py-pdf/pypdf/releases/tag/6.1.3). ### Workarounds If you cannot upgrade yet, consider applying the changes from PR [#3502](https://github.com/py-pdf/pypdf/pull/3502).
### Impact An attacker who uses this vulnerability can craft a PDF which leads to an infinite loop. This requires parsing the content stream of a page which has an inline image using the DCTDecode filter. ### Patches This has been fixed in [pypdf==6.1.3](https://github.com/py-pdf/pypdf/releases/tag/6.1.3). ### Workarounds If you cannot upgrade yet, consider applying the changes from PR [#3501](https://github.com/py-pdf/pypdf/pull/3501).
Cybersecurity researchers have disclosed details of a coordinated spear-phishing campaign dubbed PhantomCaptcha targeting organizations associated with Ukraine's war relief efforts to deliver a remote access trojan that uses a WebSocket for command-and-control (C2). The activity, which took place on October 8, 2025, targeted individual members of the International Red Cross, Norwegian Refugee
### Impact This vulnerability allows malicious actors to force the application server to send HTTP requests to both external and internal servers. In certain cases, this may lead to access to internal resources such as databases, file systems, or other services that are not supposed to be directly accessible from the internet. The overall impact of this vulnerability is considered limited, as the functionality is highly restricted and only processes IMG tags. #### Description Server-Side Request Forgery (SSRF) is a vulnerability that enables a malicious actor to manipulate an application server into performing HTTP requests to arbitrary domains. SSRF is commonly exploited to make the server initiate requests to its internal systems or other services within the same network, which are typically not exposed to external users. In some cases, SSRF can also be used to target external systems. A successful SSRF attack can result in unauthorized actions or access to data within the organiza...
Cisco Talos has observed increased activity by malicious actors leveraging Direct Send as part of phishing campaigns. Here's how to strengthen your defenses.
The threat actors behind a malware family known as Winos 4.0 (aka ValleyRAT) have expanded their targeting footprint from China and Taiwan to target Japan and Malaysia with another remote access trojan (RAT) tracked as HoldingHands RAT (aka Gh0stBins). "The campaign relied on phishing emails with PDFs that contained embedded malicious links," Pei Han Liao, researcher with Fortinet's FortiGuard
Cisco Talos has uncovered a new attack linked to Famous Chollima, a threat group aligned with North Korea (DPRK).
### Summary The mitigation proposed in GHSA-37j7-fg3j-429f for disabling eval/Function when executing untrusted code in happy-dom does not suffice, since it still allows prototype pollution payloads. ### Details The untrusted script and the rest of the application still run in the same Isolate/process, so attackers can deploy prototype pollution payloads to hijack important references like "process" in the example below, or to hijack control flow via flipping checks of undefined property. There might be other payloads that allow the manipulation of require, e.g., via (univeral) gadgets (https://www.usenix.org/system/files/usenixsecurity23-shcherbakov.pdf). ### PoC Attackers can pollute builtins like Object.prototype.hasOwnProperty() to obtain important references at runtime, e.g., "process". In this way, attackers might be able to execute arbitrary commands like in the example below via spawn(). ```js import { Browser } from "happy-dom"; const browser = new Browser({settings: {enab...
An Elasticsearch leak exposed 6 billion records from global data breaches and scraping sources, including banking and personal details tied to multiple regions.
Cybersecurity researchers have shed light on a previously undocumented threat actor called TA585 that has been observed delivering an off-the-shelf malware called MonsterV2 via phishing campaigns. The Proofpoint Threat Research Team described the threat activity cluster as sophisticated, leveraging web injections and filtering checks as part of its attack chains. "TA585 is notable because it
