Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: None: There is no loss of confidentiality within the impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: High: There is total loss of availability, resulting in the attacker being able to fully deny access to resources in the impacted component; 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 impacted component (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).

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 9 Nov 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

Until a fix is available, avoid passing untrusted or unbounded input strings containing long whitespace runs to ParseDate(), Date::Manip::Date->parse(), or ->parse_time().

Description

Date::Manip versions through 7.00 for Perl contain a vulnerability that allows an attacker to cause CPU exhaustion via quadratic backtracking in the _parse_time function. This occurs when parsing strings with long runs of whitespace, leading to denial of service by consuming excessive CPU resources. The vulnerability affects calls to ParseDate(), Date::Manip::Date->parse(), or ->parse_time() with untrusted, unbounded input strings.

Impact

An attacker can cause a denial of service by forcing the affected functions to consume excessive CPU resources during parsing. This can degrade or halt service availability for applications using vulnerable versions of Date::Manip when processing untrusted input strings containing long whitespace runs.

Summary

The vulnerability in Date::Manip (CVE-2026-60075) arises from the _parse_time function's use of an unanchored substitution regex that attempts to remove time patterns from anywhere in the input string. The regex engine retries matching at every position of an interior whitespace run, causing quadratic backtracking. Because the leading whitespace match consumes greedily and the time pattern alternation fails, the engine backtracks one space at a time, resulting in CPU usage that grows quadratically with the length of the whitespace run. This allows an attacker to cause CPU exhaustion and denial of service by providing input strings with long whitespace sequences, even if no actual time is present.
