Recent research has revealed three new security vulnerabilities in Sitecore Experience Platform that could potentially be exploited to achieve information disclosure and remote code execution. The vulnerabilities, which include HTML cache poisoning through unsafe reflections, insecure deserialization, and information disclosure in ItemService API with a restricted anonymous user, were disclosed by watchTowr Labs researchers who warned of the potential for attackers to craft an exploit chain using these flaws to gain unauthorized access to sensitive information or execute malicious code on the platform. This latest discovery serves as a reminder of the importance of staying informed about emerging vulnerabilities and prioritizing robust security measures in order to safeguard systems from cyber threats.
WatchTowr Labs discovered three new security vulnerabilities in Sitecore Experience Platform, including information disclosure and remote code execution. The vulnerabilities, CVE-2025-53693, CVE-2025-53691, and CVE-2025-53694, can be chained together to create a complex exploit chain. Patches for the first two vulnerabilities were released in June 2025, while the third was released in July 2025. Successful exploitation of these flaws could result in severe security breaches and unauthorized access to sensitive information. Cybersecurity professionals must remain vigilant and stay up-to-date with the latest patches and advisories to safeguard systems from emerging threats.
In a world where cybersecurity is an ever-evolving game, researchers and experts alike must constantly be on the lookout for emerging threats. The latest in this ongoing saga comes from watchTowr Labs, which has disclosed three new security vulnerabilities in Sitecore Experience Platform that could potentially be exploited to achieve information disclosure and remote code execution.
These findings are part of a larger pattern where researchers have been sounding the alarm on various platforms, including Apache ActiveMQ, Wazuh, and Docker, highlighting the need for vigilance when it comes to patching software systems. The Sitecore vulnerabilities, specifically CVE-2025-53693, CVE-2025-53691, and CVE-2025-53694, demonstrate how easily an attacker can exploit these flaws to gain unauthorized access to sensitive information or execute malicious code on the platform.
According to watchTowr Labs researcher Piotr Bazydlo, the newly uncovered bugs could be fashioned into an exploit chain by bringing together the pre-auth HTML cache poisoning vulnerability with a post-authenticated remote code execution issue. This creates a complex sequence of events that can lead to serious security breaches.
The first vulnerability, CVE-2025-53693, involves HTML cache poisoning through unsafe reflections. According to Bazydlo, "We managed to abuse a very restricted reflection path to call a method that lets us poison any HTML cache key." This primitive allowed the researchers to hijack Sitecore Experience Platform pages and then drop arbitrary JavaScript to trigger a post-authenticated remote code execution vulnerability.
The second vulnerability, CVE-2025-53691, is related to remote code execution through insecure deserialization. Bazydlo explained that this vulnerability was chained with the first one, resulting in malicious HTML code that ultimately led to code execution via an unrestricted BinaryFormatter call.
The third and final vulnerability, CVE-2025-53694, involves information disclosure in ItemService API with a restricted anonymous user, leading to exposure of cache keys using a brute-force approach. This was identified as a critical flaw by watchTowr Labs, which stated that "successful exploitation of the related vulnerabilities might lead to remote code execution and non-authorized access to information."
Sitecore released patches for the first two vulnerabilities in June 2025 and the third in July 2025, with the company warning that successful exploitation of these flaws could result in severe security breaches. While this is a sobering reminder of the need for vigilance when it comes to cybersecurity, experts note that the constant cat-and-mouse game between researchers and attackers highlights the importance of staying informed about emerging vulnerabilities.
As experts continue to sound the alarm on various platforms, including Sitecore, Docker, and Wazuh, one thing becomes increasingly clear: the threat landscape is a constantly evolving and complex web. Cybersecurity professionals must remain vigilant, stay up-to-date with the latest patches and advisories, and prioritize the implementation of robust security measures in order to safeguard systems from these emerging threats.
In the face of such threats, organizations cannot afford to be complacent or naive when it comes to their cybersecurity posture. Rather, they must adopt a proactive approach that involves continuous monitoring, vulnerability assessment, and penetration testing. By staying informed about emerging vulnerabilities like those discovered in Sitecore Experience Platform, companies can better protect themselves against cyber threats and ensure the integrity of their systems.
The ongoing saga of emerging vulnerabilities serves as a stark reminder of the ever-present threat landscape. Cybersecurity experts will undoubtedly continue to sound the alarm on these emerging threats, emphasizing the need for vigilance and proactive measures in order to safeguard systems from the ever-present risk of exploitation.
