CVE-2024-52798
ADVISORY - githubSummary
Impact
The regular expression that is vulnerable to backtracking can be generated in the 0.1.x release of path-to-regexp
, originally reported in CVE-2024-45296
Patches
Upgrade to 0.1.12.
Workarounds
Avoid using two parameters within a single path segment, when the separator is not .
(e.g. no /:a-:b
). Alternatively, you can define the regex used for both parameters and ensure they do not overlap to allow backtracking.

CVSS:4 Severity and metrics
The CVSS metrics represent different qualitative aspects of a vulnerability that impact the overall score, as defined by the CVSS Specification.
Attack Vector (AV)
Network
Attack Vector (AV)
Network
The vulnerable component is bound to the network stack, but the attack is limited at the protocol level to a logically adjacent topology. This can mean an attack must be launched from the same shared physical (e.g., Bluetooth or IEEE 802.11) or logical (e.g., local IP subnet) network, or from within a secure or otherwise limited administrative domain (e.g., MPLS, secure VPN to an administrative network zone). One example of an Adjacent attack would be an ARP (IPv4) or neighbor discovery (IPv6) flood leading to a denial of service on the local LAN segment (e.g., CVE-2013-6014).
Attack Complexity (AC)
Low
Attack Complexity (AC)
Low
Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success when attacking the vulnerable component.
Attack Requirements (AT)
None
Attack Requirements (AT)
None
The successful attack does not depend on the deployment and execution conditions of the vulnerable system. The attacker can expect to be able to reach the vulnerability and execute the exploit under all or most instances of the vulnerability.
Privileges Required (PR)
None
Privileges Required (PR)
None
The attacker is unauthenticated prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
User Interaction (UI)
None
User Interaction (UI)
None
The vulnerable system can be exploited without interaction from any human user, other than the attacker. Examples include: a remote attacker is able to send packets to a target system a locally authenticated attacker executes code to elevate privileges.
Confidentiality Impact to the Vulnerable System (VC)
None
Confidentiality Impact to the Vulnerable System (VC)
None
There is no loss of confidentiality within the Vulnerable System.
Confidentiality Impact to the Subsequent System (SC)
None
Confidentiality Impact to the Subsequent System (SC)
None
There is no loss of confidentiality within the Subsequent System or all confidentiality impact is constrained to the Vulnerable System.
Integrity Impact to the Vulnerable System (VI)
None
Integrity Impact to the Vulnerable System (VI)
None
There is no loss of integrity within the Vulnerable System.
Integrity Impact to the Subsequent System (SI)
None
Integrity Impact to the Subsequent System (SI)
None
There is no loss of integrity within the Subsequent System or all integrity impact is constrained to the Vulnerable System.
Vulnerable System Availability Impact (VA)
High
Vulnerable System Availability Impact (VA)
High
There is a total loss of availability, resulting in the attacker being able to fully deny access to resources in the Vulnerable System; this loss is either sustained (while the attacker continues to deliver the attack) or persistent (the condition persists even after the attack has completed). Alternatively, the attacker has the ability to deny some availability, but the loss of availability presents a direct, serious consequence to the Vulnerable System (e.g., the attacker cannot disrupt existing connections, but can prevent new connections; the attacker can repeatedly exploit a vulnerability that, in each instance of a successful attack, leaks a only small amount of memory, but after repeated exploitation causes a service to become completely unavailable).
Subsequent System Availability Impact (SA)
None
Subsequent System Availability Impact (SA)
None
There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.
