Hackers are actively exploiting CVE-2025-49113, a critical vulnerability in the widely used Roundcube open-source webmail application that allows remote execution.
The security issue has been present in Roundcube for over a decade and impacts versions of Roundcube webmail 1.1.0 through 1.6.10. It received a patch on June 1st.
It took attackers just a couple of days to reverse engineer the fix, weaponize the vulnerability, and start selling a working exploit on at least one hacker forum.
Roundcube is one of the most popular webmail solutions as the product is included in offers from well-known hosting providers such as GoDaddy, Hostinger, Dreamhost, or OVH.
"Email armageddon"
CVE-2025-49113 is a post-authentication remote code execution (RCE) vulnerability that received a critical severity score of 9.9 out of 10 and is described as “email armageddon.”
It was discovered and reported by Kirill Firsov, the CEO of the cybersecurity company FearsOff, who decided to publish the technical details before the end of the responsible disclosure period because an exploit had become available.

The Akamai Security Intelligence Response Team (SIRT) has been monitoring activity surrounding CVE-2024-4577, a PHP vulnerability that affects installations running CGI mode that was disclosed in June 2024.
The vulnerability primarily affects Windows installations using Chinese and Japanese language locales, but it is possible that the vulnerability applies to a wider range of installations.
As early as one day after disclosure, the SIRT observed numerous exploit attempts to abuse this vulnerability, indicating high exploitability and quick adoption by threat actors.
The exploitations include command injection and multiple malware campaigns: Gh0st RAT, RedTail cryptominers, and XMRig.
Akamai App & API Protector has been automatically mitigating exploits that target our customers.
In this blog post, we’ve included a comprehensive list of indicators of compromise (IOCs) for the various exploits we discuss.
A few months ago, I stumbled upon a 24 years old buffer overflow in the glibc, the base library for linux programs. Despite being reachable in multiple well-known libraries or executables, it proved rarely exploitable — while it didn't provide much leeway, it required hard-to-achieve preconditions. Looking for targets lead mainly to disappointment. On PHP however, the bug shone, and proved useful in exploiting its engine in two different ways.
Detect and mitigate CVE-2024-4577, a critical remote code execution vulnerability in PHP CGI. Organizations are advised to patch urgently.
While implementing PHP, the team did not notice the Best-Fit feature of encoding conversion within the Windows operating system. This oversight allows unauthenticated attackers to bypass the previous protection of CVE-2012-1823 by specific character sequences. Arbitrary code can be executed on remote PHP servers through the argument injection attack.
Orange Tsai tweeted a few hours ago about “One of [his] PHP vulnerabilities, which affects XAMPP by default”, and we were curious to say the least. XAMPP is a very popular way for administrators and developers to rapidly deploy Apache, PHP, and a bunch of other tools, and any bug
An online tool offers a service to obfuscate PHP code, but it also silently inserts a backdoor into the code that allows any other PHP code to be executed!
A critical severity vulnerability in a WordPress plugin with more than 90,000 installs can let attackers gain remote code execution to fully compromise vulnerable websites.
We recently discovered a vulnerability in Composer, the main package manager for PHP, and were able to use it to take over the central repository, packagist.org.
CVE-2022-35650
The vulnerability was found in Moodle, occurs due to input validation error when importing lesson questions. This insufficient path checks results in arbitrary file read risk. This vulnerability allows a remote attacker to perform directory traversal attacks. The capability to access this feature is only available to teachers, managers and admins by default.
This week, immensely popular PyPI package 'ctx' has been compromised and altered to steal environment variables from its users. Additionally, a forked PHP project 'phpass' also suffered a repo-hijacking attack with the project tained with identical malicious payload.
