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: Changed: An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
Confidentiality: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the impacted component.
Availability: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the impacted component are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 1 May 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponized: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

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

Apply the official patches provided by Ubuntu by updating libphp-adodb to version 5.22.9 or later. The updates are available for multiple Ubuntu releases including 16.04 LTS, 18.04 LTS, 20.04 LTS, 22.04 LTS, and 24.04 LTS. Standard system updates will apply the necessary fixes. No additional mitigation is required once patched.

Description

ADOdb, a PHP database abstraction library, contains a critical vulnerability prior to version 5.22.9 where improper escaping of query parameters can allow remote attackers to execute arbitrary SQL commands when connecting to PostgreSQL databases and using pg_insert_id() with user input. This flaw has been patched in version 5.22.9. The vulnerability has a CVSS score of 10.0, indicating critical severity with network attack vector, no privileges required, no user interaction, and impacts confidentiality, integrity, and availability. Ubuntu has released security updates for multiple supported releases to address this issue.

Impact

Remote attackers can execute arbitrary SQL commands on PostgreSQL databases via vulnerable ADOdb versions, potentially leading to full compromise of database confidentiality, integrity, and availability. This can result in unauthorized data access, data modification, or denial of service.

Summary

ADOdb versions prior to 5.22.9 improperly escape query parameters, enabling remote attackers to execute arbitrary SQL statements when the library connects to PostgreSQL databases and calls pg_insert_id() with user-supplied data. This vulnerability can lead to full compromise of the database confidentiality, integrity, and availability. The issue is fixed in version 5.22.9 and corresponding Ubuntu package updates. The vulnerability has a CVSS 3.1 score of 10.0 (critical), reflecting its severity and ease of exploitation without privileges or user interaction.
