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

Attack Vector: Network: The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, 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: The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Attack Requirements: 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: None: The attacker is unauthorized 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: None: The vulnerable system can be exploited without interaction from any human user, other than the attacker.
Vulnerable system confidentiality: None: There is no loss of confidentiality within the Vulnerable System.
Vulnerable system integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact to the Vulnerable System.
Vulnerable system availability: None: There is no impact to availability within the Vulnerable System.
Subsequent system confidentiality: None: There is no loss of confidentiality within the Subsequent System or all confidentiality impact is constrained to the Vulnerable System.
Subsequent system integrity: None: There is no loss of integrity within the Subsequent System or all integrity impact is constrained to the Vulnerable System.
Subsequent system availability: None: There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.

Exploitation evidence

CVE published 3 Feb 2026
Detectable: no evidence on record.
No public nuclei template indexed

No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.

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 2026-10-25.

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.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC 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

1. Upgrade pearweb to version 1.33.0 or later immediately to apply the official patch addressing the SQL injection vulnerability. 2. Conduct a thorough code review of all PHP applications using pearweb components to identify and remediate any unsafe SQL query constructions, especially those involving dynamic IN (...) lists. 3. Implement parameterized queries or prepared statements wherever possible to prevent SQL injection risks. 4. Deploy web application firewalls (WAFs) configured to detect and block SQL injection attempts targeting known vulnerable endpoints. 5. Enforce strict input validation and sanitization on all user-supplied data, particularly inputs that influence database queries. 6. Monitor application logs and network traffic for unusual query patterns or injection attempts. 7. Educate development teams on secure coding practices related to database interactions to prevent similar vulnerabilities in the future. 8. Establish a patch management process to ensure timely updates of third-party components like pearweb.

Description

CVE-2026-25236 is a medium-severity SQL injection vulnerability affecting pearweb versions prior to 1.33.0. The flaw arises from improper neutralization of special elements in SQL commands, specifically unsafe literal substitution in karma queries for an IN (... ) list. This vulnerability allows an unauthenticated attacker to execute arbitrary SQL queries remotely without user interaction, potentially leading to limited data integrity impact. The issue has been patched in version 1.33.0. Although no known exploits are currently reported in the wild, organizations using vulnerable pearweb versions should prioritize updating to mitigate risk.

Impact

For European organizations, this vulnerability poses a risk primarily to web applications built on PHP that incorporate pearweb components prior to version 1.33.0. Successful exploitation could allow attackers to manipulate database queries, potentially leading to data corruption or unauthorized data modification. While the vulnerability does not directly compromise confidentiality or availability, the integrity impact could disrupt business operations, especially for applications relying on karma queries for critical functionality. Organizations in sectors such as finance, healthcare, and e-commerce, where data integrity is paramount, could face operational disruptions or reputational damage if exploited. The remote, unauthenticated nature of the vulnerability increases the risk of automated scanning and exploitation attempts, particularly on public-facing web servers. Given the absence of known exploits, the immediate risk is moderate, but delayed patching could increase exposure. The impact is compounded in environments lacking robust input validation and web application firewalls.

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.
