CVE-2025-12970

The extractname function in Fluent Bit indocker input plugin copies container names into a fixed size stack buffer without validating length. An attacker who can create containers or control container names, can supply a long name that overflows the buffer, leading to process crash or arbitrary...

CVE-2025-12978

Fluent Bit inhttp, insplunk, and inelasticsearch input plugins contain a flaw in the tagkey validation logic that fails to enforce exact key-length matching. This allows crafted inputs where a tag prefix is incorrectly treated as a full match. A remote attacker with authenticated or exposed acces...

AZL-71111 CVE-2025-12970 affecting package fluent-bit for versions less than 3.1.10-2

The extractname function in Fluent Bit indocker input plugin copies container names into a fixed size stack buffer without validating length. An attacker who can create containers or control container names, can supply a long name that overflows the buffer, leading to process crash or arbitrary...

AZL-71108 CVE-2025-12969 affecting package fluent-bit for versions less than 3.1.10-4

Fluent Bit inforward input plugin does not properly enforce the security.users authentication mechanism under certain configuration conditions. This allows remote attackers with network access to the Fluent Bit instance exposing the forward input to send unauthenticated data. By bypassing...

New Fluent Bit Flaws Expose Cloud to RCE and Stealthy Infrastructure Intrusions

Cybersecurity researchers have discovered five vulnerabilities in Fluent Bit, an open-source and lightweight telemetry agent, that could be chained to compromise and take over cloud infrastructures. The security defects "allow attackers to bypass authentication, perform path traversal, achieve...

CVE-2025-12972 CVE-2025-12972

Fluent Bit outfile plugin does not properly sanitize tag values when deriving output file names. When the File option is omitted, the plugin uses untrusted tag input to construct file paths. This allows attackers with network access to craft tags containing path traversal sequences that cause...

CVE-2025-12972

CVE-2025-12972 affects Fluent Bit, specifically the out_file plugin. When the File option is omitted, untrusted tag input is used to build output file paths, and tags containing path traversal sequences can cause files to be written outside the intended directory. This may enable unauthorized fil...
