An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-49975 exists.\n\nAffected packages and fixed versions:\n- apache (Bitnami): affected from 2.4.17; fixed in 2.4.68\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-49975/ (Markdown: https://insights.sbomify.com/CVE-2026-49975/index.md)","id":"CVE-2026-49975","markdown":"https://insights.sbomify.com/CVE-2026-49975/index.md","name":"CVE-2026-49975","record":{"aliases":["ALPINE-CVE-2026-49975","ALSA-2026:25057","ALSA-2026:25090","ALSA-2026:25225","AZL-89510","AZL-89550","AZL-89760","BELL-CVE-2026-49975","BIT-apache-2026-49975","CLSA-2026-1781259837","CLSA-2026-1781511735","CLSA-2026-1782153735","CLSA-2026-1782317138","CLSA-2026-1782317575","CLSA-2026-1782317620","CLSA-2026-1783525080","CLSA-2026-1783632803","CLSA-2026-1783633126","CLSA-2026-1783791892","CLSA-2026-1783791996","CLSA-2026-1783792262","CLSA-2026-1787249757","CLSA-2026-1787249820","CLSA-2026-1787250962","CLSA-2026-1787250980","CLSA-2026-1787251196","CLSA-2026-1787251292","CLSA-2026-1787251300","CLSA-2026-1787251550","CLSA-2026-1787251557","CLSA-2026-1790158682","CLSA-2026-1790236505","CLSA-2026-1790262589","DEBIAN-CVE-2026-49975","ECHO-c67b-44b0-ff31","GHSA-262v-g5h9-6mc6","MINI-97wj-wmfr-hrwh","OESA-2026-2611","OESA-2026-2627","OESA-2026-2638","OESA-2026-2639","OESA-2026-2640","RHSA-2026:25057","RHSA-2026:25090","RHSA-2026:25225","RLSA-2026:25057","RLSA-2026:25090","RLSA-2026:25225","UBUNTU-CVE-2026-49975","USN-8384-1","USN-8398-1","USN-8398-3","USN-8398-4"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Apache HTTP Server","requires_auth":"none","summary":"Attackers can cause denial of service in Apache HTTP Server by sending malicious HTTP requests that trigger excessive memory allocation.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"http_server","vendor":"apache"},{"product":"debian_linux","vendor":"debian"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-409","name":"Improper Handling of Highly Compressed Data (Data Amplification)"},{"id":"CWE-789","name":"Memory Allocation with Excessive Size Value"}],"description":"Memory Allocation with Excessive Size Value vulnerability in Apache HTTP Server's mod_http leads to denial of service via malicious HTTP requests.\n\nThis issue affects Apache HTTP Server: from 2.4.17 through 2.4.67.","ecosystems":["AlmaLinux:10","AlmaLinux:8","AlmaLinux:9","Bitnami","Red Hat:enterprise_linux:10.2","Red Hat:enterprise_linux:8::appstream","Red Hat:enterprise_linux:9::appstream","Rocky Linux:10","Rocky Linux:8","Rocky Linux:9"],"exploits":{"exploitdb":0,"first_seen":"2026-06-03","github_poc":14,"max_poc_stars":29,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-06-04T06:22:54Z","kind":"github_poc","ref":"https://github.com/mrx-arafat/CVE-2026-49975-POC","stars":29,"title":"HTTP/2 Bomb PoC — CVE-2026-49975 (HPACK indexed reference bomb + flow-control stall)"},{"date":"2026-06-10T05:06:42Z","kind":"github_poc","ref":"https://github.com/EQSTLab/CVE-2026-49975","stars":14,"title":"HTTP/2 Bomb"},{"date":"2026-06-03T20:22:30Z","kind":"github_poc","ref":"https://github.com/fevar54/Proof-of-Concept-POC---CVE-2026-49975-HTTP-2-Bomb-","stars":6,"title":"PoC de CVE-2026-49975 (HTTP/2 Bomb): DoS remoto contra servidores web con HTTP/2 por defecto."},{"date":"2026-06-10T12:52:47Z","kind":"github_poc","ref":"https://github.com/LSG-PolarBear/CVE-2026-49975","stars":6,"title":"CVE-2026-49975漏洞复现"},{"date":"2026-06-05T01:08:17Z","kind":"github_poc","ref":"https://github.com/obrige/http2-bomb","stars":4,"title":"CVE-2026-49975 HTTP/2 Stream Amplification — Docker PoC with Web Console"},{"date":"2026-06-10T17:26:30Z","kind":"github_poc","ref":"https://github.com/LiaoZiqi-GZFLS/CVE-2026-49975","stars":3,"title":"CVE-2026-49975"},{"date":"2026-09-16T07:21:14Z","kind":"github_poc","ref":"https://github.com/naheeju/POC-CVE-2026-49975","stars":3,"title":"Security research PoC for CVE-2026-49975: HTTP/2 HPACK compression bomb + flow-control hold DoS in Apache mod_http2"},{"date":"2026-06-08T14:44:32Z","kind":"github_poc","ref":"https://github.com/renzi25031469/CVE-2026-49975-HTTP-2-Bomb","stars":2,"title":"Disclosed on June 3, 2026, the \"HTTP/2 Bomb\" is an unauthenticated remote DoS that combines an HPACK compression bomb with a Slowloris-style hold to exhaust server memory.
