CVE-2025-31632 is a high-severity vulnerability classified under CWE-98, which pertains to improper control of filenames used in include or require statements within PHP programs. Specifically, this vulnerability affects the SpyroPress La Boom product, versions up to 2.7. The flaw allows for PHP Local File Inclusion (LFI), which occurs when an attacker can manipulate the filename parameter in an include or require statement to load unintended files from the local filesystem. Although the description mentions 'PHP Remote File Inclusion,' the actual impact is local file inclusion, which can still lead to significant security risks. Exploiting this vulnerability requires no authentication (PR:N) and no user interaction (UI:N), but the attack complexity is high (AC:H), indicating some difficulty in exploitation, possibly due to environment-specific conditions or input sanitization that is partially effective. The vulnerability has a CVSS v3.1 base score of 8.1, reflecting high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). Successful exploitation could allow an attacker to read sensitive files, execute arbitrary code, or cause denial of service by including malicious or system files. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability was reserved in March 2025 and published in May 2025, indicating recent discovery. The lack of patch links suggests that organizations using La Boom should urgently monitor for vendor updates or apply temporary mitigations. The root cause is insufficient validation or sanitization of input controlling the filename in PHP include/require statements, a common issue in PHP applications that can lead to critical security breaches if exploited.

For European organizations using SpyroPress La Boom, this vulnerability poses a significant risk. The ability to perform local file inclusion can lead to unauthorized disclosure of sensitive data, including configuration files, credentials, or personal data protected under GDPR. It can also enable remote code execution if attackers can include files containing malicious code, leading to full system compromise. This threatens confidentiality, integrity, and availability of affected systems. Given the high CVSS score and no authentication requirement, attackers could exploit this vulnerability remotely over the network, increasing the attack surface. Organizations in sectors with high-value data such as finance, healthcare, and government are particularly at risk. Additionally, the vulnerability could be leveraged as a foothold for lateral movement within networks, escalating the impact. The absence of known exploits currently provides a window for proactive defense, but the high severity demands immediate attention to prevent potential exploitation. The impact is exacerbated in environments where La Boom is integrated with other critical systems or where security monitoring is limited.

Organizations should immediately inventory their use of SpyroPress La Boom and identify affected versions (up to 2.7). Until an official patch is released, apply the following mitigations: 1) Implement strict input validation and sanitization on all parameters controlling file inclusion to restrict input to a whitelist of allowed files or paths. 2) Employ web application firewalls (WAFs) with rules designed to detect and block suspicious include/require parameter manipulations. 3) Restrict PHP file inclusion directives by disabling allow_url_include and setting open_basedir to limit accessible directories. 4) Monitor logs for unusual file access patterns or errors related to include/require statements. 5) Isolate vulnerable applications in segmented network zones to limit potential lateral movement. 6) Prepare for rapid deployment of vendor patches once available and test updates in controlled environments before production rollout. 7) Educate developers and administrators about secure coding practices related to file inclusion to prevent recurrence. These targeted steps go beyond generic advice by focusing on the specific nature of the vulnerability and the PHP environment.
