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 4 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

Users should avoid passing untrusted input via the -func parameter or apply manual sanitization until an official fix is released.

Description

SQL::Abstract versions from 1.90_01 up to but not including 2.000001_04 for Perl contain a vulnerability where the injection_guard check is skipped for function names passed using the -func parameter. This allows untrusted function names to be inserted into SQL queries without proper sanitization, potentially leading to SQL injection.

Impact

An attacker can exploit this vulnerability to inject malicious SQL code by supplying crafted function names through the -func parameter. This can lead to unauthorized data access or manipulation if the application relies on injection_guard for sanitization and uses the vulnerable versions of SQL::Abstract.

Summary

The vulnerability in SQL::Abstract affects versions from 1.90_01 before 2.000001_04. The injection_guard mechanism, which is intended to sanitize function names to prevent SQL injection, is bypassed when function names are provided explicitly via the { -func => [ $name, ... ] } syntax. Only the shorthand { -name => ... } form is properly checked. Applications relying on injection_guard to validate untrusted function names passed with -func are vulnerable to SQL injection attacks.

CWE-89Improper Neutralization of Special Elements used in an SQL Command (SQL Injection) (opens in a new tab)
Base weaknessLikelihood of exploit: HighCWE Top 25 (2025): #2OWASP Top 10 A05:2025: Injection (opens in a new tab)
The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
Architecture and Design · Libraries or Frameworks
Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
Architecture and Design · Parameterization
If available, use structured mechanisms that automatically enforce the separation between data and code. These mechanisms may be able to provide the relevant quoting, encoding, and validation automatically, instead of relying on the developer to provide this capability at every point where output is generated.
Architecture and Design · Operation · Environment Hardening
Run your code using the lowest privileges that are required to accomplish the necessary tasks. If possible, create isolated accounts with limited privileges that are only used for a single task. That way, a successful attack will not immediately give the attacker access to the rest of the software or its environment.
