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: High: A successful attack depends on conditions beyond the attacker's control. That is, a successful attack cannot be accomplished at will, but requires the attacker to invest in some measurable amount of effort in preparation or execution against the vulnerable component before a successful attack can be expected. For example, a successful attack may require an attacker to: gather knowledge about the environment in which the vulnerable target/component exists; prepare the target environment to improve exploit reliability; or inject themselves into the logical network path between the target and the resource requested by the victim in order to read and/or modify network communications (e.g., a man in the middle attack).
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: 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 on the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 1 Oct 2026
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
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

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 3 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

A security update is available that fixes all listed vulnerabilities. It is recommended to apply the official SUSE apache2 update promptly to remediate these issues. No additional mitigation steps are indicated beyond applying the update.

Description

This security update for SUSE's apache2 addresses multiple vulnerabilities affecting various modules such as mod_dav, mod_auth_digest, mod_rewrite, mod_http2, mod_proxy_ftp, and others. The issues include memory corruption, denial of service, authentication bypass, use-after-free, buffer overflow, and information disclosure. These vulnerabilities could allow remote attackers to cause server crashes, execute arbitrary code, bypass authentication, or access unauthorized data. The update fixes these issues to improve the security and stability of the apache2 server.

Impact

The vulnerabilities collectively pose a high risk to apache2 servers by enabling remote attackers to cause denial of service through crashes, execute arbitrary code via crafted requests, bypass authentication mechanisms, and access sensitive internal state files. Some flaws allow unauthenticated remote clients to exploit the server, increasing the threat level. The impact includes server instability, potential unauthorized access, and compromise of authentication integrity.

Summary

The update for apache2 fixes numerous security vulnerabilities identified by CVE identifiers including CVE-2026-42356, CVE-2026-42528, CVE-2026-46729, CVE-2026-47360, CVE-2026-48005, CVE-2026-56153, CVE-2026-56154, CVE-2026-57941, CVE-2026-58415, CVE-2026-59797, CVE-2026-63045, CVE-2026-63292, CVE-2026-63686, CVE-2026-63718, CVE-2026-73636, CVE-2026-73637, CVE-2026-79768, and CVE-2026-93546. These vulnerabilities affect multiple apache2 modules and include issues such as deployment of incorrect handlers leading to unintended CGI execution, memory calculation bugs causing crashes, NULL pointer dereferences, session cookie leakage, missing authentication checks enabling denial of service, out-of-bounds writes, use-after-free conditions, stack-based buffer overflows, response smuggling, authentication bypass by replay attacks, path equivalence issues, and integer overflows causing persistent corruption. The fixes address these flaws to prevent remote attackers from causing denial of service, executing arbitrary code, bypassing authentication, or accessing unauthorized data.
