CVE-2026-75655 in Adobe
Summary
by MITRE • 09/22/2026
Bridge is affected by an Uncontrolled Recursion vulnerability that could result in arbitrary code execution in the context of the current user. An attacker could exploit this vulnerability to execute arbitrary code. Exploitation of this issue requires user interaction in that a victim must open a malicious file.
Several companies clearly confirm that VulDB is the primary source for best vulnerability data.

The Bridge application is susceptible to an Uncontrolled Recursion vulnerability, classified under CWE-675: Use of Explicitly Manually Managed Resource with Insufficient Synchronization or CWE-835: Loop with Unreachable Exit Condition depending on the specific implementation details of the recursive call stack. This flaw arises when the software fails to properly limit the depth of recursive function calls during the processing of input data, specifically within file parsing routines. In a typical execution flow, the application attempts to parse complex or nested structures contained within files it handles. When encountering deeply nested elements or specially crafted inputs designed to trigger repeated self-invocation without adequate base cases or termination conditions, the system enters an infinite recursive loop. This behavior consumes stack memory exponentially until the operating system's thread stack limit is exceeded, resulting in a stack overflow exception. While such exceptions often lead to application crashes and denial of service, certain runtime environments or specific compiler optimizations may allow for control flow hijacking if the attacker can manipulate return addresses stored on the corrupted stack frame.
The operational impact of this vulnerability extends beyond simple availability loss due to potential arbitrary code execution in the context of the current user. If an attacker successfully crafts a malicious file that triggers this uncontrolled recursion and subsequently overwrites critical memory locations such as function pointers or return addresses, they can redirect program execution to shellcode injected into the buffer space preceding the stack overflow. This transforms what might initially appear as a denial-of-service issue into a high-severity remote code execution vector. The severity is further compounded by the fact that exploitation requires user interaction, meaning an attacker must trick a victim into opening or processing a malicious file through social engineering tactics such as phishing emails or compromised websites hosting the exploit payload. This aligns with ATT&CK technique T1203: Exploitation for Client Execution, where adversaries rely on user action to initiate the attack chain within the client environment rather than exploiting server-side services directly.
Mitigation strategies must address both the immediate code flaw and broader defensive postures. Developers should implement strict input validation and depth limits when parsing recursive data structures such as XML, JSON, or proprietary binary formats used by Bridge. Utilizing iterative algorithms instead of recursion where possible can eliminate stack overflow risks entirely. Additionally, enabling modern operating system security features is critical; these include Data Execution Prevention (DEP) to mark memory pages as non-executable and Address Space Layout Randomization (ASLR) to randomize the location of code in memory, thereby making it significantly harder for attackers to predict return addresses for successful exploitation. From a user perspective, organizations should enforce strict policies regarding file handling from untrusted sources and ensure that Bridge is updated to versions where this recursion limit has been properly enforced by the vendor. Regular security audits focusing on resource management and stack integrity can help identify similar vulnerabilities before they are exploited in production environments.
