CVE-2025-48324 is a Stored Cross-Site Scripting (XSS) vulnerability classified under CWE-79, affecting the khashabawy tli.tl auto Twitter poster software up to version 3.4. This vulnerability arises due to improper neutralization of input during web page generation, allowing malicious scripts to be injected and stored within the application. When other users or administrators access the affected pages, the malicious payload executes in their browsers, potentially leading to session hijacking, credential theft, or unauthorized actions performed on behalf of the victim. The vulnerability is exploitable remotely over the network (AV:N), requires low attack complexity (AC:L), but does require high privileges (PR:H) and user interaction (UI:R). The scope is changed (S:C), indicating that the vulnerability affects resources beyond the initially vulnerable component. The impact includes low confidentiality, integrity, and availability impacts, consistent with typical Stored XSS attacks. No known exploits are currently in the wild, and no patches have been published yet. The vulnerability was reserved in May 2025 and published in August 2025, indicating recent discovery. The tli.tl auto Twitter poster is a tool used to automate posting to Twitter, likely used by social media managers or marketing teams to schedule and manage tweets automatically. Stored XSS in such a tool could allow attackers to compromise accounts, manipulate posted content, or spread malware via trusted social media channels.

For European organizations using the tli.tl auto Twitter poster, this vulnerability poses a risk of account compromise and reputational damage. Attackers exploiting Stored XSS could hijack administrative sessions, post unauthorized tweets, or steal sensitive information from users with elevated privileges. This could lead to misinformation dissemination, brand damage, and potential regulatory scrutiny under GDPR if personal data is exposed or misused. The requirement for high privileges to exploit somewhat limits the attack surface to insiders or compromised accounts, but the risk remains significant in environments where multiple users have elevated access. The vulnerability could also be leveraged as a pivot point for further attacks within an organization’s social media infrastructure. Given the interconnected nature of social media and marketing platforms, exploitation could have cascading effects on customer trust and operational continuity.

1. Immediate mitigation should include restricting access to the tli.tl auto Twitter poster to trusted administrators only, minimizing the number of users with high privileges. 2. Implement strict input validation and output encoding on all user-supplied data within the application to neutralize malicious scripts. 3. Monitor and audit logs for unusual activity or unauthorized postings to detect potential exploitation early. 4. Employ Content Security Policy (CSP) headers to limit the execution of unauthorized scripts in browsers. 5. If possible, isolate the application environment and limit its network access to reduce the impact of a successful attack. 6. Engage with the vendor or community to obtain patches or updates addressing this vulnerability as soon as they become available. 7. Educate privileged users about the risks of phishing and social engineering that could lead to privilege escalation or account compromise. 8. Consider alternative tools with a stronger security posture if patching is delayed.
